I think it would be ideal to have it all. Autonomous cars acting as taxis for cheap when you arrive in a city and also high speed rail lines as alternatives to flights to get to another city. Autonomous buses will basically be the new electric street cars. Do their route, stop and plug themselves in to charge, then off to take over a route when needed.<p>That will happen. What&#x27;s going to be difficult is the high speed rail to compete against the airlines. I would really prefer an alternative to air travel myself. I hate it and the type of people that seem to be in airports from security to passengers.
