How Self-Driving Cars will Destroy Cities (and what to do about it)

Not Just Bikes has a new video out: How Self-Driving Cars will Destroy Cities (and what to do about it). I have a love/hate relationship with urbanist essayists like this. On the one hand, they often raise issues that most of the time are not explicitly considered by most people. On the other hand, they tend to have a very leftist perspective, and ignore important costs, benefits, and solutions.

The video makes roughly the following arguments:

  1. If you don't have to pay attention to the road, you can do other things while in transit. This lowers the effective cost of traveling a given distance. As a consequence, there will be more demand for road space, increasing congestion.
  2. Because autonomous cars are so technology-laden, the market will favor a few large companies that offer a subscription model. There are several consequences of this, which can be summarized as: laws will favor the companies rather than the public.
  3. Getting into doomer territory, car makers might succeed in banning human drivers and pedestrians from most roadways, and increase speed limits to ridiculous levels, causing noise pollution and other problems. They might also get public transit banned (I'm not sure how this would happen but that's the argument).

Externalities

1 and 3 are similar problems. There are externalities that current laws don't address because they weren't huge problems given historical technology. Namely noise, tire pollution, and congestion. But new technology, autonomous cars, changes the costs and benefits of driving and will make these externalities much worse.

Not Just Bikes's proposed solution is to completely ban anything related to cars from city centers: highways, roads, parking spaces, parking garages. Bans are the same blunt tool that current laws use to force too much parking and not enough housing and bikes lanes to be built, just in the opposite direction. But he redeems himself by proposing putting a price on driving.

If you've ever heard of Arthur Pigou, a price on driving as the solution to 1 and 3 is pretty obvious. If someone really wants to drive at 4:30pm on a Friday when everyone else in the city wants to drive too, let them pay extra to be one of the people who can actually get places. There's a limit to how many people can actually get anywhere at that time, and we might as well offer the slots to the people who get the most value from it, and get some money back for public use in return. Charging a congestion fee completely solves the problem of autonomous vehicles circling the city hoping to be closest to the next customer. They have to pay the same fee as anyone else, so they'll only be on the road if they're the highest-value use of road space.

Not Just Bikes proposes investing in "functional and viable public transit", especially in forms that are difficult to remove, presumably to be able to resist transient political pressure. Of course, any publicly-run agency is going to have a very hard time running "functional and viable" transit when compared to a selfish private organization. And there's no reason a company that makes autonomous vehicles can't make and run buses as well.

A better solution is to price road space appropriately, and be agnostic to who's using the space. This allows the highest-value uses without artificially restricting to "public" or "autonomous" uses. Offer express lanes that guarantee certain speeds by limiting the number of vehicles that can enter. The entry fee is set high enough that there aren't any queues to enter. Crucial here is that any vehicle, private or public, should be able to use the lane as long as the driver pays the fee. This allows many more solutions to transit problems, without the dysfunction of publicly-run bus agencies. For example, corporate shuttles, church buses, and private rideshares should be allowed to use the same express lanes as public buses. And if Jay Leno wants to drive his personal car in the express lane, as long as he pays the fee, let him! Same goes for autonomous vehicle makers. If they want to reserve some space on freeways for their cars, make them compete on price the same as anyone else.

Putting a market-based fee on express lanes has a side benefit of making the opportunity cost of formerly transit-only lanes more legible. A few such market-based lanes can illustrate how expensive existing transit-only lanes really are.

Public Choice

Point 2, that laws will tend to favor autonomous car makers over the public, is just a specific example of public choice being a hard problem. There are analogous situations with Big Tech and the public commons, John Deere and right-to-repair, and Big Oil and climate regulations. I don't have a lot to say here, except that this has always been a problem, in other times and places has been much worse, and is likely to be manageable. People are smart.

An Aside on Congestion and Induced Demand

This video mentions the old chestnut that (paraphrasing) induced demand means it's pointless to increase road capacity. I'll quote one of our own:

Likewise a new freeway lane immediately filling up tells us there are still more people who want to be using this freeway.

If autonomous vehicles lead to people traveling more, that's good! It means more trips are now worth taking. People are visiting friends and relatives more often, working at jobs that are farther away but are a better fit for them, and in general doing more valuable things.

Conclusion

I'd like to see more discussion of the economics of transit, and economic solutions, especially without a leftist slant. But this is the first time I've seen a popular urbanist talk about the fact that self-driving cars will increase road use and congestion. This is great! This fact should be obvious to anyone who's spent five seconds thinking about the consequences of making driving cheaper, but I haven't seen it mentioned much outside rationalist circles. This point alone makes up for any other failings in this video.

Time, on October 22nd: "Don’t Trust the Political Prediction Markets". Oops.

When it comes to accuracy, these prediction markets have an even poorer historical track record than political polling– not to mention these companies come and go with startling transience.

the reality is that the Circuit Court could well rule that these platforms are illegal and shut them down in merely a few weeks’ time.

Maybe they would last longer if Time wasn't writing hit pieces on them.
