I'm not very excited by autonomous cars, at least for short-trip personal transport, as I don't think they're solving the real problem which is to not need cars in the first place.

However it's far far easier for commercial companies to invest $billions in them than it is for governments to invest $billions in the infrastructure to make cars redundant. Look at the bitching and moaning that happens whenever a new train line is proposed.
