I didn't read the entire piece...
People think the autonomous car is going to solve a lot of the current problems; Accidents, Parking, Congestion. It kind of makes me giggle a bit, as I ponder what may happen. That is, the conclusions drawn from "self-driving" vehicles are possibly way over cooked.
The certification process for these cars are going to be very, very expensive. Think about the software involved for the operation of aircraft and the review / testing process then apply it for the road. That is level of scrutiny that will be placed on "self-driving" vehicles.
Hacking, equipment failures, environmental surprises and more will be sure to keep a healthy portion of the public skeptical and possibly downright hostile to the idea for at least a decade, post certification, in my opinion. "Self-driving" will be contained and tightly regulated.
What people on the coasts forget about is, really, the rest of the country. The people that actually enjoy driving, where parking isn't a problem, and congestion takes place in the morning and after work, but only lasts about 5 minutes. Metro areas of > 2 million people don't have much problems with traffic in flyover country... at least not when compared to the coasts.
The counter arguments to the piece are plentiful for the foreseeable future.
