Latest / Talking Michigan Transportation / Feds ease rules to expedite deployment of robotaxis
Transcript
- 0:07Jeff Cranson: Hello, welcome to the Talking Michigan Transportation Podcast.
- 0:10Jeff Cranson: I'm Jeff Cranson.
- 0:12Jeff Cranson: This week I had a chance to catch up again with Joann Muller, the Detroit-based author of the Axios Future Mobility Newsletter.
- 0:23Jeff Cranson: She's been covering the automotive industry for some time and evolved into an expert on all things going on with technology and changes in mobility.
- 0:34Jeff Cranson: She's always interesting.
- 0:36Jeff Cranson: This week we talked about some reporting that she's done on Amazon's Zoox robotaxis and how the federal government has granted them some temporary exemptions to commercially deploy up to 2,500 more of those robotaxis annually for two years.
- 0:52Jeff Cranson: And we'll also talk about her latest road trip to Wisconsin in Rivian and what she found out about the technology and whether range anxiety is becoming less of a concern in driving electric vehicles.
- 1:05Jeff Cranson: We'll also talk about other things related to the federal government and U.S.
- 1:10Jeff Cranson: DOT Secretary Sean Duffy's uh his initiative to expedite the deployment of automated vehicles of all kinds by uh looking at streamlining the rules and regulations and a few other things that we touch base on that she's been reporting on recently and that you can read about in her newsletter.
- 1:28Jeff Cranson: So I hope you enjoyed the conversation.
- 1:31Jeff Cranson: So again, I'm with Joann Muller.
- 1:33Jeff Cranson: A couple things I wanted to really catch up on lately.
- 1:36Jeff Cranson: You've been writing a lot of stories about Zoox, which is Amazon's Robo Taxi venture.
- 1:41Jeff Cranson: Um, it kind of feels like between what Amazon's doing and what uh what Tesla is doing with Elon Musk and obviously Waymo and Google.
- 1:51Jeff Cranson: It's like, are those the new big three?
- 1:55Joann Muller: Well, actually, yeah, it's funny.
- 1:57Joann Muller: I I uh I didn't put Zoox in the big three.
- 2:00Joann Muller: Uh I recently wrote a story that said the new big three are um Waymo, Tesla, and Uber.
- 2:08Joann Muller: Uh and the reason I said Uber is because they're partnering with everybody on autonomous vehicles, uh, because they kind of see them as a threat to their traditional business.
- 2:20Joann Muller: Um but in any case, Zoox is a is an important player.
- 2:24Joann Muller: Uh they were a startup Amazon bottom because they saw the possibilities there.
- 2:30Joann Muller: And they are different from any other company right now because they designed a purpose-built uh robo taxi, has no steering wheel, no pedals, no human at all.
- 2:42Joann Muller: And so it's been a little bit harder to get approval to deploy that, but they just got the green light, uh, at least for a limited fleet from the federal government.
- 2:53Jeff Cranson: Yeah, talk a little bit more about that.
- 2:54Jeff Cranson: Sean Duffy, who's the secretary of the U.S.
- 2:57Jeff Cranson: Department of Transportation, has uh made this a point for more than a year now that he's gonna push for expediting these kinds of approvals.
- 3:05Jeff Cranson: And some would say easing regulations, and maybe that's not a term that they like, or maybe they do if you think all regulations are red tape.
- 3:12Jeff Cranson: But could you talk more about that?
- 3:14Joann Muller: Yeah, sure.
- 3:15Joann Muller: I mean, so yes, the transportation secretary is a big believer in autonomous vehicles, uh, not only from a safety standpoint, but also like, you know, he wants to make sure the U.S.
- 3:27Joann Muller: industry is strong from a national security standpoint.
- 3:31Joann Muller: So what the Trump administration is doing, and particularly Secretary Duffy and the NHSA uh administrator, uh Jonathan Morrison, they are trying to very rapidly clear out a lot of rules that were written years, decades ago about motor vehicle safety that refer to cars with steering wheels and pedals.
- 3:56Joann Muller: Um and the idea here is if you are having a car that uh doesn't have a human in it, why do you need side view mirrors?
- 4:05Joann Muller: Why do you need windshield wipers?
- 4:07Joann Muller: Why do you need a steering wheel or brake pedals?
- 4:09Joann Muller: And so they're like basically modernizing the rule book for um for the modern car, which doesn't have a driver.
- 4:19Joann Muller: They're still requiring that the stopping distance still has to be the same.
- 4:24Joann Muller: If you're stopping a vehicle with a computer, you got to show that it can perform as well as uh a human hitting the brake.
- 4:33Joann Muller: And so they're trying to be careful and thoughtful about this, but they also are removing these obstacles to innovation.
- 4:42Jeff Cranson: It seems like a little bit of a needle to thread because Sean Duffy and the Federal Highway Administration have put so much emphasis on safety and that they want, you know, everything, they want roads and all mobility to be safer.
- 4:54Jeff Cranson: And obviously, anybody that believes in this knows that AVs ultimately are gonna be safer for all the reasons that we talk about all the time.
- 5:02Jeff Cranson: They don't have road rage, they don't get drunk, they don't fall asleep.
- 5:05Jeff Cranson: Um, and nobody likes to think that a computer can drive better than they can, but I firmly believe that.
- 5:11Jeff Cranson: But is it, you know, a little bit of backsliding first?
- 5:15Jeff Cranson: Because there's gonna be things that happen as you deploy these rapidly and as you do ease the regulations.
- 5:20Jeff Cranson: So, I mean, is that a bit of a contradiction that ultimately we're trying to get to a safer environment?
- 5:25Joann Muller: You know, I I wouldn't necessarily call it a a backslide uh or a contradiction.
- 5:31Joann Muller: I think that the technology itself uh is remarkable and will in fact make the roads safer.
- 5:41Joann Muller: But what as they're scaling now, and we're seeing this in particular with Waymo because they're far ahead of everyone else, there's a lot of stuff that keeps coming up that nobody seemed to anticipate.
- 5:53Joann Muller: Uh-oh, a robotaxi just drove into a flood zone.
- 5:57Joann Muller: Uh-oh, robotaxi didn't uh there was a big power outage in San Francisco, and a bunch of cars got stuck, and then every human car got stuck behind them.
- 6:09Jeff Cranson: And drove over fireworks, yeah.
- 6:11Joann Muller: Drive over fireworks.
- 6:12Joann Muller: These are problems for sure.
- 6:15Joann Muller: Not minimizing that these are problems, but the you know, they're working through them.
- 6:23Joann Muller: It's a bit of scary.
- 6:25Joann Muller: Let's deploy them and and then find the problems, you know.
- 6:29Joann Muller: This is how Silicon Valley works.
- 6:32Joann Muller: But overall, you look at the data that's come in so far.
- 6:36Joann Muller: Waymo has been very transparent with their own research.
- 6:40Joann Muller: Um, and you know, generally speaking, there's a lot of good signs about how this uh excuse me, how this technology will um will actually be safer.
- 6:52Joann Muller: But you know, the jury's still out, the consumer has to be convinced.
- 6:57Joann Muller: And so, you know, uh headlines about driving over fireworks are not good for building public trust.
- 7:05Jeff Cranson: Yeah, let me just read this because it's one of the more intriguing leads I've read in a while.
- 7:08Jeff Cranson: It was in a New York Times story that you linked in Axios Mobility and said it.
- 7:12Jeff Cranson: On July 4th, more than 100,000 people packed San Francisco's waterfront for a foggy fireworks show over the Golden Gate Bridge.
- 7:21Jeff Cranson: When they tried to go home, Waymo got in the way.
- 7:24Jeff Cranson: With crowds milling around, Waymo's driverless cars blocked intersections and choked traffic.
- 7:29Jeff Cranson: Some drivers were stuck behind the electric robotaxis for more than three hours.
- 7:34Jeff Cranson: Several Waymo's had to be towed after their batteries died in the gridlock.
- 7:37Jeff Cranson: At least two drove over exploding fireworks with one catching fire.
- 7:42Jeff Cranson: So how do you not read that whole story?
- 7:45Joann Muller: Well, and what one of the things that I think is uh coming to light that is underappreciated is the importance of the human remote monitors for these vehicles.
- 7:59Joann Muller: So these are people who are sitting in an office somewhere, and when a robotaxi gets into trouble, it pings this office and says, Hey, there's a there's a big crowd of people here at this uh fireworks exhibit or show, or the lights, the traffic lights just went out, or there's a police situation.
- 8:20Joann Muller: I'm not sure what is the right thing to do.
- 8:22Joann Muller: And at that point, the human gets engaged with uh through cameras and through other technology to figure out what's happening, and they sort of lay breadcrumbs to say, all right, here's the route you should take.
- 8:36Joann Muller: They are not taking control of the vehicle remotely.
- 8:40Joann Muller: Um, that is definitely not happening.
- 8:42Joann Muller: But these humans, I think we're not appreciating how important they are and how many of them we probably need to oversee these fleets as they grow.
- 8:53Joann Muller: And in the case, in many of these cases, anyways, where the Waymo's have ended up blocking traffic, it's because there weren't enough humans who could come to their rescue fast enough remotely and tell them what to do.
- 9:07Joann Muller: And so the system got overwhelmed.
- 9:09Joann Muller: And that is a problem that yeah, the back office got overwhelmed.
- 9:14Joann Muller: And this is a problem that needs to be solved.
- 9:17Joann Muller: And there's a lot of attention to the fact that some of Waymo's people are located in the Philippines.
- 9:24Joann Muller: So this is a big concern, and I think there's a big movement to try to make sure all those people are are in the United States.
- 9:33Joann Muller: In fact, the other big location, they have some in Phoenix, some in the Philippines, and some in Metro Detroit.
- 9:40Jeff Cranson: Yeah, I guess I knew there was a presence in Metro Detroit, but I didn't know how.
- 9:43Jeff Cranson: So you think it it could be growing as as they realize that they need to be more based more domestically?
- 9:49Jeff Cranson: Is that what you're doing?
- 9:50Joann Muller: Well, there's a big call for more remote people to jump in or or at least a better system to have the remote uh supervision.
- 10:01Joann Muller: Um, whether that turns into more jobs for Michigan, I don't know.
- 10:04Joann Muller: I have not heard anything like that, but it's possible.
- 10:08Jeff Cranson: So this didn't really get on my radar until um I came to the department in 2011.
- 10:15Jeff Cranson: Um, and and our director at the time, Kirk Steudle, was very interested.
- 10:18Jeff Cranson: He was an early pioneer on this technology, testifying before Congress.
- 10:22Jeff Cranson: In fact, I wrote some testimony for him in 2016, and we talked then about uh one of the things I emphasized was not having to take the keys away from an elderly parent or grandparent someday.
- 10:33Jeff Cranson: That the freedom of mobility that AVs promise us.
- 10:36Jeff Cranson: Um, do you think we proceeded at about the rate you would have guessed, or do you think it's taking longer to get there than you might have thought?
- 10:44Joann Muller: Well, I think it took a long time to get to here.
- 10:47Joann Muller: Um now it's really seems to be starting to accelerate.
- 10:52Joann Muller: Um I think the technology is maturing.
- 10:56Joann Muller: I don't know I would call it mature yet, but I think there's still a lot of, you know, really, this is a very tiny segment of the total cars on the road.
- 11:06Joann Muller: So we got to keep that in perspective.
- 11:08Joann Muller: Um, but there's a there's a lot of uh sort of old-fashioned infrastructure stuff that has to happen to support autonomous vehicles, you know.
- 11:18Joann Muller: You need the the depots uh where these cars are gonna get charged and cleaned and maintained.
- 11:24Joann Muller: There that takes a lot of human effort, right?
- 11:28Joann Muller: And um, you know, someday some of that may be automated.
- 11:32Joann Muller: There are charging companies out there now that can take the cable and actually use a robot to plug it into the car.
- 11:39Joann Muller: So, you know, uh, but but who is a robot gonna clean up the vomit or the dirty diaper on the floor?
- 11:45Joann Muller: I don't know.
- 11:46Jeff Cranson: Well, not to mention the repairs that go on, and this and this this is not something that your average auto mechanic is trained for.
- 11:52Jeff Cranson: And Washington Community College was early in on a program to train the workforce to work on these kinds of cars and the sensors.
- 12:00Jeff Cranson: Of course, it's hard to keep up with that because things keep changing so quickly.
- 12:03Jeff Cranson: So I'm guessing that's a big challenge for them.
- 12:05Jeff Cranson: But I think you raise you raise a really good point that um there's still gonna be humans involved all the way around.
- 12:12Jeff Cranson: Um, I I'm still a big believer that ultimately this is gonna be safer.
- 12:16Jeff Cranson: I wonder if you think people, as the adoption grows and usually it's at a higher end, like most new technology, just like it was with EVs and will be with AVs, are those people gonna be willing to pay, you know, fees or or tolls to have a dedicated lane to drive their AV?
- 12:34Joann Muller: Um, that's possible.
- 12:35Joann Muller: Um right now we're not seeing a lot of dedicated, you know, the the business model isn't for dedicated lanes just yet.
- 12:44Joann Muller: Uh, you know, we do have this uh this connected car lane and uh through uh uh western Wayne County um that cavenue is doing.
- 12:54Joann Muller: Yeah.
- 12:55Joann Muller: Um you know, whether that someday becomes only for autonomous vehicles, I don't know.
- 13:01Joann Muller: I'm I'm not sure exactly how it's going to right right now robo taxis make the most sense in a dense urban city, which is you know where taxis and rideshare are are most important too.
- 13:16Joann Muller: And so if you can keep them moving around, you know, in theory that could be efficient.
- 13:22Joann Muller: There's a lot of questions about how they impact cities, and and we'll find that out as time goes on.
- 13:29Joann Muller: Um but I uh, you know, I think what's what we need to think about is how can AVs serve neighborhoods and communities that don't have a lot of money, you know, like can it become a transportation option for people, let's say in the city of Detroit that aren't served by a bus line?
- 13:49Joann Muller: You know?
- 13:50Jeff Cranson: No, I think you're there's a real economic imperative here.
- 13:53Jeff Cranson: I think I agree completely.
- 13:54Jeff Cranson: Please stay tuned.
- 13:56Jeff Cranson: We'll be back with more talking Michigan transportation right after this.
- 14:00MDOT Message: Avoid the wait and remember the Mackinac Bridge is closed to traffic Labor Day for the annual bridge walk starting at 6 30 a.m.
- 14:07MDOT Message: Spend some extra time in the UP or take your time heading north since the bridge won't reopen to traffic until noon to allow walkers to clear the bridge.
- 14:16MDOT Message: For more information, head to Mackinacbridge.org/ walk.
- 14:21Jeff Cranson: Uh, let's talk about your latest road trip.
- 14:24Jeff Cranson: You took a Rivian to Wisconsin.
- 14:26Jeff Cranson: I don't know.
- 14:26Jeff Cranson: Did you go pretty far north in Wisconsin?
- 14:29Joann Muller: Yeah, we went up to the Door Peninsula, uh well into the woods up there to uh to a uh some a place that called the Northern Sky Theater, which is up in uh Fish Creek, uh, Wisconsin.
- 14:43Joann Muller: Um and uh we took the ferry across uh the the Lake Express ferry from Biskegan to Manitoba.
- 14:50Joann Muller: From Bispegan to Milwaukee, yeah, yeah, which was phenomenal.
- 14:55Joann Muller: It was very expensive though.
- 14:56Joann Muller: I mean, it costs as much as it would have to fly, but uh it was on my bucket list, so I wanted to do it.
- 15:02Joann Muller: But the Rivian, uh, this is the brand new R2, which is their new uh sort of mid-sized um electric SUV, super, super important to Rivian's chances for success.
- 15:16Joann Muller: And uh truthfully, it was terrific.
- 15:19Jeff Cranson: Uh yeah, it sounds like you didn't have any range anxiety.
- 15:24Joann Muller: No, no, you know, and that's a reflection of the fact that the charging networks out there have improved so much and the opening of the Tesla network to uh other cars.
- 15:35Joann Muller: Um Rivian is one of the first uh vehicles to have the Tesla style port, charging port on it.
- 15:44Joann Muller: Um, and that is how a lot of um companies are uh are going.
- 15:50Jeff Cranson: Yeah, so why did Tesla do that?
- 15:52Jeff Cranson: What advantage did they finally see in making that uh making that available to other vehicles?
- 15:58Joann Muller: Well, um, you know, Tesla has always said its goal is to electrify the the entire nationwide fleet of cars.
- 16:08Joann Muller: So, you know, you could argue, oh, it's altruistic.
- 16:11Joann Muller: Uh they also make money, you know, they're selling access to their charging network, but not all of it.
- 16:17Joann Muller: It's only about, I I want to say, it's less than half, whatever it is.
- 16:21Joann Muller: But the their network is so reliable and so uh ubiquitous that, you know, other companies were jumping at this chance to have their cars be able to be charged there because it means GM can sell more EVs if they have if their customers can go to the um you know to the to the Tesla charger.
- 16:44Joann Muller: And and I was saying that um so Rivian is one of the first companies to have a Knack style uh port on the uh on their car.
- 16:54Joann Muller: That's the Tesla style port.
- 16:56Joann Muller: And that's like key.
- 16:59Joann Muller: Once you have the port on the car matching the the plug on the charger, it becomes very seamless.
- 17:06Joann Muller: Right now, because the whole industry is moving toward Tesla's standard, that you have to everybody's has to use adapters, you know, to make A and B talk to each other.
- 17:19Joann Muller: And there can be some problems with adapters, as you can imagine.
- 17:24Joann Muller: You know, it's not an ideal situation.
- 17:27Joann Muller: Um when it is fully uh when it's A to A, it's brilliant and wonderful.
- 17:35Joann Muller: And that's what I experienced with the Tesla, uh with the Rivian at a Tesla charger.
- 17:42Joann Muller: And by the way, all of GM's new uh EVs uh have that port.
- 17:47Joann Muller: Ford is going to that uh technology.
- 17:50Joann Muller: Literally everyone in the industry is, and so you know, another year or so uh probably we'll be will be there uh in a way.
- 18:00Joann Muller: And the charging companies are also adapting the Tesla standard.
- 18:05Joann Muller: So everybody's getting on the same page here very soon, and that will make it very easy.
- 18:10Jeff Cranson: It'd be almost like you could charge every phone and tablet and other device with a USB C, right?
- 18:16Joann Muller: Yeah.
- 18:17Joann Muller: Although you know how annoying it is that Apple constantly changes, you know, you had uh the C and now you have the whatever they call the new thing.
- 18:26Joann Muller: Uh, you know.
- 18:26Jeff Cranson: Um exactly.
- 18:28Jeff Cranson: That's uh there's there's obviously an economic reason for that.
- 18:31Jeff Cranson: But uh I I want to explore more um what you think is going on from a policy standpoint because the charging network, because again, Sean Duffy and the federal government said uh, you know, we don't like Nevi, but it's too far down the tracks for us to stop it now, so you know they let it go ahead.
- 18:49Jeff Cranson: Um but there's still that uh anti-EV sentiment out there.
- 18:54Jeff Cranson: So do you just see that gradually fading away?
- 18:58Joann Muller: You know, I I have come to realize that Nevi is not that important.
- 19:02Joann Muller: Um, it was a big signal uh during the Biden administration that EVs are great, let's go for it.
- 19:13Joann Muller: We're gonna put these uh we're gonna have this policy where we have to have every state has to have EV uh chargers along the highway.
- 19:22Joann Muller: And it was really like um uh a security blanket for consumers, it was a signal for consumers.
- 19:30Joann Muller: But the fact of the matter is the vast majority of chargers that are being built today are being built with private capital and not with government money, like the vast majority of them.
- 19:41Joann Muller: And the network is so much better because the charging companies are spending the money, they're not spending the government money.
- 19:48Joann Muller: Now, one interesting thing that I did see like once a state does spend their government the the Nevi money that you know, this is the federal money program for fast chargers along the highway.
- 20:01Joann Muller: Once they're once their highway is well electrified, they can then use that money in uh for charging in other places.
- 20:10Joann Muller: And uh, you know, we'll see how states spend that.
- 20:16Joann Muller: But in Florida, for instance, they are putting it toward charging for uh electric air taxis.
- 20:24Joann Muller: Interesting.
- 20:25Joann Muller: And I found that really interesting because Florida says that's where we want to lead, you know.
- 20:30Joann Muller: I don't know where Michigan stands right now on spending its NEBI money, but it is not as important as the private capital that's getting spent.
- 20:40Joann Muller: That's the point I want your listeners to know.
- 20:43Jeff Cranson: Well, and I think that that kind of says that both sides were right, right?
- 20:47Jeff Cranson: You send a signal and you tell the marketplace that that we believe in this and we're gonna support you, and then the marketplace does what it's gonna do, which is uh you know, create the infrastructure and find an incentive for them, which they're doing.
- 21:00Jeff Cranson: So it's it's all good, I think.
- 21:03Jeff Cranson: Um, lastly, just a little bit related to Rivian, um, I want to talk about uh your dispatch on the the headlights.
- 21:10Jeff Cranson: I think that's just really fascinating.
- 21:12Jeff Cranson: Um, sounds like it's great from a safety standpoint, and you know, why did it take so long to get here?
- 21:18Joann Muller: So Rivian is equipped with uh these adaptive beam headlights.
- 21:23Joann Muller: Um what is important to know is that these headlights have been around forever on European cars and in Europe and other parts of the world too.
- 21:32Joann Muller: But they came originally on Audi's, BMWs, Mercedes, those kinds of cars.
- 21:36Joann Muller: And what they do is they kind of use a matrix layout of LED lights, and they can selectively turn off some of those lights that might be shining in another motorist's eyes.
- 21:50Joann Muller: Um, and so what it means is if you're driving a car, you can, with these headlights, you can leave your high beams on all the time and you see everything, but there's a little shadow over the oncoming car.
- 22:04Joann Muller: Not it doesn't block it out or anything, it just puts it in a little box, a little shadow box, which means you can still see the car, but the car is not being blinded by your bright headlights.
- 22:14Joann Muller: Now, why did it take so long?
- 22:16Joann Muller: It's because the US regulations just differ from uh from the rest of the world.
- 22:25Joann Muller: And finally, uh the the Congress in in the Infrastructure Act back in 2021 said, all right, U.S.
- 22:34Joann Muller: NHTSA, you need to uh authorize these.
- 22:38Joann Muller: You need to find a rule that says these these headlights are now uh legal because they're provably safer.
- 22:46Joann Muller: And the problem is the law went into effect in 23, but the law is so complex and there's so much red tape around it that uh the car makers say they can't really pass the test.
- 23:00Joann Muller: And so Rivian, which is, as you know, a new company, and they said, you know what, we can just start from scratch and design these lights to work with the new rule.
- 23:10Joann Muller: And they basically did, and that's why Rivian is first.
- 23:13Joann Muller: Uh Tesla has now put it on their newer cars, and the Europeans have gone back and redesigned their system, so they're all bringing it in the next year, too.
- 23:22Joann Muller: But it's it's ridiculous that the United States is 10 years behind Europe when it comes to headlights.
- 23:28Jeff Cranson: Well, this is gonna have to propel the other automakers to to do it and get on board.
- 23:32Jeff Cranson: I mean, I don't know why NHTSA doesn't just mandate it the way they did with backup cameras.
- 23:37Jeff Cranson: That that seems like the ultimate solution.
- 23:39Joann Muller: Yeah, but they should have written an easier law, like a simpler law that you can abide by, you know.
- 23:45Joann Muller: I mean, they they had uh there was an SAE agreement on what it should be, and then somehow they made it more complicated than it needed to be.
- 23:53Jeff Cranson: Well, let me just read real quickly, your I thought you painted a wonderful picture of your experience.
- 23:58Jeff Cranson: You said Rivian's headlights lit up a family of raccoons on a pitch black Wisconsin Road, then reshaped their beam around another car to avoid blinding its driver without dimming the road ahead.
- 24:09Jeff Cranson: That's uh really, really well put, and uh I like that.
- 24:12Jeff Cranson: So Joanne, thank you as always for taking time to talk about these things.
- 24:17Jeff Cranson: I always like touching bass with you, and I really appreciate uh your intellectual curiosity about everything going on, and it's uh it's gonna continue at a rapid pace.
- 24:26Jeff Cranson: I think we're just gonna see evolution after evolution.
- 24:29Joann Muller: Absolutely.
- 24:30Joann Muller: Well, thank you for having me, and I appreciate your interest in Axios.
- 24:34Jeff Cranson: I'd like to thank you once more for tuning in to Talking Michigan Transportation.
