Why wouldn't driverless cars have the exact same problems? A driverless car is pretty expensive, so it needs to be making money a high fraction of the time or it's not economical for a company to invest in it, just like a regular taxi service (I'm really curious how they would handle 'surge' times - have fleets of cars that sit parked and unused 99% of the time??). Uber and Lyft actually have a lot of flexibility in this regard, since the cars already exist for other reasons (and don't cost Uber/Lyft anything when they're not driving). The idea that 'driverless' somehow means 'lots of cars, everywhere, at all times, very cheap' doesn't make any sense to me from an economics perspective.
