I think that is true, I actually see these companies moving into the mass transit business themselves. It is already starting with "UberPool". I could easily see Uber buying underground transit lines to run their own dedicated service in a few decades. Sure you will have the option for the premium Uber service where you are driven all the way from A to B in your own private pod. But many will choose the value-priced "UberX" option that shares your ride with others and / or connects you with a scheduled Uber-partnered (or owned) mass-transit vehicle.

And then the additional benefit is this will make a denser lifestyle more appealing. Going between places in the city by car will now be easier and cheaper because you don't have to deal with parking. Land dedicated to parking will no longer be needed on anywhere near the scale it is today. Even in the suburbs, the massive parking lots can be drastically reduced and we will likely see parking disappearing many places there too. All of this will feed back onto itself and car ownership will be less and less appealing. Even take a typical suburban home. All of that land area taken up by the driveway and garage can go away. Plus it will be more appealing to have the house closer to the street so you have a shorter walk to your taxi every day.

The rise of self-driving cars will bring a lot of big changes to our cities. Not unlike the rise of cars themselves. But many of the trends will be reversed.

Interesting points.

“Another related technology, in a lot of ways, is the elevator,” said Chris Urmson, the head of Google’s self-driving-car project. “It’s another technology that had a fairly profound impact on cities.”

Urmson’s not the only one to make this comparison. Elon Musk, the CEO of Tesla, has compared driverless cars to elevators, too.

Elevators didn’t just change people’s perceptions, they changed how humans physically move through buildings and cities. Whereas it was once more desirable to live and work closer to the ground—as someone who once lived on the seventh floor of a walk-up in New York, I know this to be true—elevators made higher floors more desirable.

Elevators also enabled architects to build up, up, up. The vertical aesthetic of the modern city, skyscraper-dotted horizons that double as distinct urban signatures, exist because of elevators. They created a new, and often socially awkward, kind of public space—one that feels simultaneously intimate, fleeting, and unpredictable, even as passengers know exactly where they are going.

The elevator is completely unrelated. It's on a track, occupied by a single "vehicle" at a time, with physical limitations on its movement (the ground and roof). A first-year Mechatronics student could write the control routines and assemble a fail-safe design from Radioshack and Ace Hardware in an evening!

Nonsense. Having done the design of such circuits in the early 60s I assure you that you have not the faintest understanding of that art. If you go back to the days of self service elevators being cut in you would have heard much speculation about how many people we were going to kill. And I believe we did get a few in the early days as well as some lousy performance from poorly done human factors.

The autonomous vehicle is a much more challenging effort and has much bigger societal impact. But it is clearly a parallel to the elevator. Much more interesting and unconstrained space but you still got to get the person from here to there without killing them or even subjecting them to significant grief.

How is a vehicle which can travel anywhere and amongst thousands of other vehicles also traveling the same roads in differing types of weather a parallel to a box which goes up and down in an enclosed space on a dedicated track? Not even close to the same thing. The only thing that is parallel is that both are automated and move people. Their mechanical and software systems are completely different.

They both get you from a point to another point. And both will follow a constrained route.

The autonomous vehicle is a much larger and more open problem than the elevator but both go from A to B on a constrained route.

Will Atlanta ever get driverless cars? California already has them. They've had them for like 20 years, lol.

It's not a perfect analogy but I also see a parallel in the sense that they dramatically affect how people can move in an urban environment.

The elevator is a machine allows people to traverse great vertical distances by simply pushing a button. Theoretically a driverless car could accomplish the same thing at ground level.

I thought about this the other day when I got on one of those new elevators where you select the floor in the lobby. It's my understanding that the cars are all centrally controlled in a way that is most efficient. There are no buttons or floor indicators inside the car -- you simply trust the machinery to take you to the right place.

That's like saying an apple is like a steak, because they're both food and both go down your throat.
