I fully agree: most rational nations have invested in public transportation to solve this problem. The US has a myriad of problems that has made public transportation an afterthought and not viable for most of the country. I also agree that telecommuting or flexible hours would work well. But again, for most office workers in the country and world, there is significant inflexibility: they must arrive at their appointed time, leave at their appointed time, and take breaks at appointed times. My statement was intended to be broad and to apply to all workers instead of just for the high-tech industry. So I see self-driving cars as a backdoor solution to the above problems: replace regular cars with self-driving cars, maybe with car-sharing, and now a country that has so much invested in the car suddenly is able to significantly reduce the latter's influence on society without realizing it. Well, one can but hope anyways.
