> In 20 years, most cars (electric or not) will probably be self-driving ones owned and controlled by a centralized ride-sharing service

This is not true. Just to give an example, how do you plan to implement that "centralized ride-sharing service" in a city like Cairo (current population 10+ million)? Sometimes HN users need to get out of their bubble.




Or in a city like Huntsville, AL, with a population of 200,000 and a surprising number of workers who commute from 40 or more miles away?
