"A recent study by IHS Automotive predicted that nearly every car on the road in 2050 will be self-driving; in that kind of world, in which our nation’s highways are populated by hordes of self-driving vehicles packed tightly together at higher speeds and with greater fuel efficiency, massive investments in rail infrastructure or new bus networks won’t make much sense.But these investments are already being made in places like California, which is already massively over-budget on a high-speed rail project that will be obsolete from its first day of operation."
