The OP suggests (jokingly?) that driverless cars and Musk's Hyperloop are somehow in competition. I don't see that. Cars today are about transportation and cabin conveniences. Why can't the two be separated over time? Your "car" takes your cabin to the train that takes your cabin to the high-speed rail (Hyperloop?) that takes you from Atlanta to Kansas City. Perhaps you switch cabins based on price to transport... maybe you rented a bigger one for local travel, but don't want to pay a higher price for long range travel... lots of ifs, but to me, this and/or scenario seems more likely than driverless cars vs. Hyperloops.
