  • From the passenger’s perspective, a taxi and a self-driving car are functionally identical. But back when Uber, Lyft, and the rest were offering cheap rides subsidized by VC money, all that happened was that they made traffic congestion slightly, but measurably, worse. People didn’t give up private cars in large numbers, though.

    If we get self-driving cars, then people’s private cars can add to the problem by cruising around empty most of the time, and if they’re not in them, there’s nobody to be bothered by traffic delays. The only way to achieve the dream of eliminating gridlock would be to ban private cars. And if that were politically feasible, why not just do it now with transit?








  • If it makes you feel better to believe that, go ahead. For my part, I think it’s a pretty obvious truth that when the government makes an open-access highway for everybody to use, everybody is going to use it, even in ways you may not like. Especially when it makes driving the fastest and most convenient way to get around. (Making driving on the highway faster than public transit requires lots of infrastructure, and was a deliberate policy choice.)
