The possible effects of driverless cars on cities

Posted on by

With the advent of driverless cars, here is one take on how they might transform city spaces:

Inner-city parking lots could become parks. Traffic lights could be less common because hidden sensors in cars and streets coordinate traffic. And, yes, parking tickets could become a rarity since cars would be smart enough to know where they are not supposed to be…

That city of the future could have narrower streets because parking spots would no longer be necessary. And the air would be cleaner because people would drive less. According to the National Highway Traffic Safety Administration, 30 percent of driving in business districts is spent in a hunt for a parking spot, and the agency estimates that almost one billion miles of driving is wasted that way every year…

“The future city is not going to be a congestion-free environment. That same prediction was made that cars would free cities from the congestion of horses on the street,” said Bryant Walker Smith, a fellow at the Center for Internet and Society at Stanford Law School and a member of the Center for Automotive Research at Stanford. “You have to build the sewer system to accommodate the breaks during the Super Bowl; it won’t be as pretty as we’re envisioning.”

Mr. Smith has an alternative vision of the impact of automated cars, which he believes are inevitable. Never mind that nice city center. He says that driverless cars will allow people to live farther from their offices and that the car could become an extension of home.

Interesting suggestions. Would sprawl be even more acceptable to people if they didn’t have to do the driving themselves? Pair this with the idea that there is a near endless supply of oil/gas and sprawl might be around a lot longer. I wonder if this would also lead to more cars overall and an uptick in miles driven per year, a figure that has been relatively flat in recent years.

But, I think this article doesn’t go far enough in reimagining cities with a major transportation change. Where would parking be consolidated? How might this change how buildings are designed? Are we imagining some sort of Le Corbusier world with large buildings surrounded by parks, a more New Urbanist design with plenty of dense neighborhoods where cars stay toward the outside, or something else all together?

US government behind in regulating automated features for cars

Posted on by

As car makers pursue new technologies including driverless cars, the US government is struggling to keep up with the changes:

While truly self-driving cars are years away—if they ever arrive—consumers are seeing far more car models bearing sophisticated semi-autonomous features. These include radar assisted cruise-control, which can keep a fixed distance from the car ahead; systems that warn drivers if they veer out of their lanes; and technologies that can prevent oversteering or even apply the brakes when they detect that a crash is imminent (see “Self-Driving Tech Veers into Mid-Range Cars” and “Proceed With Caution Toward the Self-Driving Car”)…

With three states and the District of Columbia having passed legislation to allow researchers to test such prototypes on real roads, Washington is grappling with how to regulate the cars. John Capp, the director of active safety systems for General Motors, says federal regulators are “trying to understand these things and trying to figure out what role they should have.”…

Unsurprisingly, NHTSA’s statement said that fully autonomous technology isn’t ready for the general public. But the fact that the agency is calling for more study is a reminder of the glacial pace of regulation: in the case of lane-departure warnings and crash-avoidance systems, it’s studying technologies that have already been on the market for several years.

See my post last week on the NHSTA statement. More broadly, this raises interesting questions about technology and the ability of regulators to keep up. For those who want to push technology forward, how much in terms of time, convenience, and dollars is lost if the government slows down the process? At the same time, how much regulation is needed to help protect the public? There is likely some sort of sweet spot when the government has time to declare technology safe and inventors and producers can still get things to the public in a reasonable amount of time…but I suspect this could vary widely across different sectors and the politics involved could change quite a bit. Take, for example, the scandal a few years back involving Toyota and the lack of findings. It cost the company quite a bit, the government still had a duty to step in, but there was little conclusion – except that perhaps we’re all going to have black boxes in our cars  soon. Imagine a few incidents like this happening with a new widespread technology like driverless cars. How much could that set the industry back and feed perceptions that the technology really wasn’t ready?

NHTSA asks states to wait on driverless cars

Posted on by

The federal government is asking states to wait on approving self-driving cars for general use until more research can be conducted:

The National Highway Traffic Safety Administration unveiled new recommendations to states for self-driving cars, urging them to be used only for testing and to require safeguards to ensure they can be taken over by a driver in the case of a malfunction.

NHTSA also said it was embarking on a four-year research effort on self-driving or autonomous vehicles as it considers requiring features like automatic braking, in which the car takes action to prevent crashes.

“We believe there are a number of technological issues as well as human performance issues that must be addressed before self-driving vehicles can be made widely available,” NHTSA said in its 14-page automated driving policy statement. “Self-driving vehicle technology is not yet at the stage of sophistication or demonstrated safety capability that it should be authorized for use by members of the public for general driving purposes. Should a state nevertheless decide to permit such non-testing operation of self-driving vehicles, at a minimum, the state should require that a properly licensed driver (i.e., one licensed to drive self-driving vehicles) be seated in the driver’s seat and be available at all times in order to operate the vehicle in situations in which the automated technology is not able to safely control the vehicle.”

NHTSA says as self-driving cars improve, they will reconsider. NHTSA says self-driving cars being tested in California, Florida and Nevada by Google and Audi of America should have the capability of detecting that their automated vehicle technologies have malfunctioned “and informing the driver in a way that enables the driver to regain proper control of the vehicle.” The Michigan Legislature is also considering allowing self-driving car testing…

Safety on the roads is an important concern but I’d be interested to see how much testing it might take for the government to approve self-driving cars. And, even if the safety appears to works out fairly quickly, will it take more time to reassure the public that such cars are safe?

It would also be interesting know how alert drivers are going to have to be while not driving. If the driver needs to be alerted to retake control, how relaxing is not driving going to be?

A summary: “driverless cars are ‘probably’ legal”

Posted on by

An economist takes a look at existing law and argues driverless cars are probably legal:

Over at the blog Marginal Revolution, economist Tyler Cowen points to a recent research paper by Bryant Walker Smith, a fellow at Stanford Law School, who has made the legality of driverless cars his bailiwick. In offering “the most comprehensive discussion to date of  whether so-called automated, autonomous, self-driving, or driverless vehicles can be  lawfully sold and used on public roads in the United States,” Smith argues that driverless cars are “probably legal.” He concludes [PDF]:

Current law probably does not prohibit  automated vehicles — but may nonetheless discourage their introduction or complicate their operation.

Unlike many journalists and policy-makers, Smith begins his analysis with a presumption of legality instead of illegality. “Until legislators, regulators, or judges definitively clarify the legal status of automated vehicles, any answer is necessarily a guess,” he writes. Smith’s own guess turns on three “key legal regimes”: the 1949 Geneva Convention on Road Traffic, National Highway Traffic Safety Administration regulations, and vehicle codes in the 50 U.S. states.

Smith doesn’t think that any of these regimes expressly prohibits driverless cars. The Geneva Convention says a driver must be able to control a vehicle at all times, but that stipulation is probably satisfied if a human can override the automatic operation. N.H.T.S.A. rules don’t explicitly rule out driverless cars either — though an odd rule saying hazard lights must be “driver controlled” might be a sticking point.

States codes, meanwhile, “probably do not prohibit” driverless cars in Smith’s mind, but they do complicate the situation. Right now these codes all naturally presume the presence of a human driver; in New York, for instance, there’s a rule that drivers must keep one hand on the wheel at all times (who knew?) that could become a problem in an automated-vehicle world. Additionally, laws dictating a certain following distance might interfere with algorithms that keep driverless cars close together on the road.

Sounds like an interesting loophole – why worry about whether it is legal when you can instead ask whether it is illegal? I still think a lot of the issue with driverless cars comes down to people, both “drivers” (now people who can override the car’s autopilot when they want) and other people on the road around the driverless cars, adjusting to the change. If it is like other modern technologies, like smartphones, and drivers realize they might be able to do other things while driving, perhaps the switch may be quick.

Another thought: could driverless cars and electric cars end up prolonging and even extending urban sprawl? If commuting is easier and consumes fewer resources (still debatable considering what it takes to produce batteries), why not continue it?

The experiences of a passenger in a driverless car

Posted on by

I have wondered about this: what is it like to be a passenger in a driverless car?

As we drove along Chicago’s South Lakeshore Drive, Muharemovic switched the car through three modes which can be selected based on what the driver wants and what the traffic situation entails…

Finally, there’s a Highly Automated mode that adds full-speed ACC with an automatic-resume function that uses free-space detection and side-sensing. This is the one we’re looking forward to.

In fully automated mode, Muharemovic completely removed his hands from the steering wheel and foot from the pedals. At one point he turned around for several seconds to talk to passengers in the backseat. He had a casualness that comes from getting used to the technology over thousands a miles and a steadfast faith in the systems he helped create…

A dyed-in-the-wool Detroit car guy, Muharemovic challenges anyone who fears that autonomous driving will take the fun out of motoring. “I’d like to meet someone who loves traffic jams,” he says, adding that his girlfriend has noticed that he comes home less stressed from his daily commute.

As this article suggests, it will likely take some time for drivers to feel comfortable letting the car do all the driving. But, once drivers see what their commute could be like, perhaps they would like the freedom.

Two other pieces of information I would like to have:

1. In fully automated mode, would traffic jams become shorter because traffic could be more evenly spaced? If so, this would be a double bonus: less traffic and not having to pay attention to whatever traffic there is.

2. I can only imagine what the early lawsuits might be like if one of these systems fails and an accident ensues or there is a glitch in the design. I was reminded the other day that nothing was ever found wrong with Toyota’s gas pedals yet they had to pay out millions in settlements. How much money could be on the line if an automatic system like this fails?

Driverless cars will lead to increased worker productivity

Posted on by

Dan Neil writes about the inevitability of driverless cars and brings up an interesting benefit: Americans will suddenly have more time on their hands.

The one brilliant part of the U.S. economic profile is productivity. It turns out, Americans are a little nutty when it comes to work.

If autonomy were fully implemented today, there would be roughly 100 million Americans sitting in their cars and trucks tomorrow, by themselves, with time on their hands. It would be, from an economist’s point of view, the Pennsylvania oil fields of man-hours, a beautiful gusher, a bonanza of reverie washing upon our shores.

In the history of human civilization, has there ever been a society to offer so much uninterrupted head space to so many? Europe’s medieval monastic tradition created scholars, true, but only a relative handful…

It’s possible that all these suddenly idle driver/passengers will waste their gift, texting, watching TV or worse. But many of them, like me, would beaver into work, happy to get a jump on the day.

And here’s the best part. I always get my best ideas in the car—in solitude, watching the unwinding of the road, hearing the thrum of the tires. You know that space, right?

Hurray – more time to work! Neil might be excited about this but I first think of all the opportunities for mixing the boundaries of home and work even further. Thinking more broadly, is productivity something we want to continue to chase as a society? Do Americans really need to be working more?

On the other hand, this could be a big boon for several sectors. Think about media companies: Americans would then have on average something like 40-60 minutes more per day to consume television shows, websites, podcasts, music, etc. Or perhaps it could give rise to all sorts of services and car add-ons; I’m thinking of the Honda Odyssey commercials from a while back showing moms going to the minivan to relax and get a facial.

 

Pedestrians in a world of driverless cars

Posted on by

Many bloggers are starting to tease out the social and infrastructure implications of driverless cars, including David Alpert over at the Atlantic:

[Driverless cars] will bring many changes, but when it comes to the car’s role in the city, they may just intensify current tensions.

David suggests that new technology will simply exacerbate current trends by “trigger[ing] a whole new round of pressure to further redesign intersections for the throughput of vehicles above all else”:

If autonomous cars travel much faster than today’s cars and operate closer to other vehicles and obstacles, as we see in the [University of] Texas team’s simulation , then they may well kill more pedestrians. Or, perhaps the computers controlling them will respond so quickly that they can avoid hitting any pedestrian, even one who steps out in front of a car.

In that case, we might see a small number of people taking advantage of that to cross through traffic, knowing the cars can’t kill him. That will slow the cars down, and their drivers will start lobbying for even greater restrictions on pedestrians, like fences preventing midblock crossings.

Our metropolitan areas could then look, more and more, like zoos for humans interlaced with pathways for the dominant species, the robot car.

Personally, I think one of these scenarios (i.e., “travel much faster…[and] kill more pedestrians”) is unlikely.  Initially, driverless cars will almost certainly be much more expensive than equivalent conventional vehicles.  A car that is both (1) more expensive and (2) more dangerous seems unlikely to sell well, to say nothing of the likelihood that such lawsuit-magnets would be sued utterly out of existence.  To catch on with a mass market, driverless cars will at least need to uphold safety’s current status quo.

As far as David’s second fear (“metropolitan areas [that] look, more and more, like zoos for humans”), I’m unclear how much that differs from current development patterns.  While there are plenty of examples of “walkable” cities, much of contemporary American infrastructure is extremely unfriendly to pedestrians, cyclists, and other non-car users.  To the extent that cars dominate today’s roads, a move to driverless cars seems only to continue, rather than augment, that trend.

The appeal of Google and its driverless cars

Posted on by

It was recently revealed that Google has been testing automated cars for some time now:

With someone behind the wheel to take control if something goes awry and a technician in the passenger seat to monitor the navigation system, seven test cars have driven 1,000 miles without human intervention and more than 140,000 miles with only occasional human control. One even drove itself down Lombard Street in San Francisco, one of the steepest and curviest streets in the nation. The only accident, engineers said, was when one Google car was rear-ended while stopped at a traffic light.

Autonomous cars are years from mass production, but technologists who have long dreamed of them believe that they can transform society as profoundly as the Internet has.

Why does this story have as much as appeal as it seems to have on the Internet? A quick argument:

This is a dream dating back decades. The futuristic exhibits of the mid 20th century had visions of this: people blissfully enjoying their trips while the cars took care of the driving. To see the dream come to fruition is satisfying and fulfilling. On a broader scale, this is part of the bigger narrative of technological progress. Although it has been delayed longer than some imagined, it demonstrates ingenuity and the progress of Americans. Since Americans have a well-established love affair with the automobile, driverless cars offers the best of all worlds: personal freedom in transportation without the need to actually do any work. And if we soon get cars that run on electricity or hydrogen, it can be completely guilt-free transportation!
