More on Driverless Cars

Closet Porsche driver Kevin Drum now argues:
Second, though, I think commuting will be changed. The hard part of carpooling right now is finding fellow passengers. With rare exceptions, it's not practical to round up a new carpool every day, so you need to find one or two people who (a) live near you, (b) work near you, (c) all work regular hours, and (d) all work the same regular hours. That's pretty hard.

Once they reach critical mass, fleets of driverless cars completely transform this. When you need a car, you click a smartphone app that immediately starts searching a central database for matches. As long as there are lots of people looking for rides—and drive time is precisely when lots of people are looking for rides—you have a pretty good chance of finding a match anytime you look for one. What's more, because the car is driverless, it has more flexibility: a human would want everyone to have destinations really close to each other, because the driver doesn't want to spend tons of extra time dropping everyone off. A driverless car doesn't care. If it has to drive a few extra miles, it's no big deal.

This is obviously better for the driver, since she can now read the paper or play Angry Birds instead of driving. It's also better for the passengers, who don't have to worry about being precisely on time every day and also don't have to worry about whether the other passengers are precisely on time. If you're running a little late, no big deal. If you work flex time, no big deal. If you have a doctor's appointment and need to leave for work an hour later than usual, no big deal.

Naivety on Driverless Cars

Felix Salmon argues that driverless cars are coming, and that this will result in massive efficiency gains:
If and when self-driving cars really start taking off, it’s easy to see where the road leads. Firstly, they probably won’t be operated on the owner-occupier model that we use for cars today....Given driverless cars’ ability to come pick you up whenever you need one, it makes much more sense to just join a network of such things....therefore the freeing up of lots of space currently given over to parking spots.

What’s more, the capacity of all that freed-up space will be much greater than the capacity of our current roads. Put enough [] self-driving cars onto the road, and it’s entirely conceivable that the number of vehicle-miles driven per hour, on any given stretch of road, could double from its current level, even without any increase in the speed limit. Then, take account of the fact that vehicle mileage will continue to improve. The result is that with existing dumb roads, we could wind up moving more people more miles for less total energy expenditure in cars — even when most of those cars continue to have just one person in them — than by forcing those people to cluster together and take huge, heavy trains instead.

3.6 Million Jobs at Risk!

Strange to say, that is not the headline of this piece in the New York Times.  Instead it's titled "Google Cars Drive Themselves, in Traffic", and starts out like this:
Anyone driving the twists of Highway 1 between San Francisco and Los Angeles recently may have glimpsed a Toyota Prius with a curious funnel-like cylinder on the roof. Harder to notice was that the person at the wheel was not actually driving.

The car is a project of Google, which has been working in secret but in plain view on vehicles that can drive themselves, using artificial-intelligence software that can sense anything near the car and mimic the decisions made by a human driver.

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.
