No problem
It shouldn't be too hard to make roads more suitable for driverless cars. First put big fences down both sides so pedestrians can't get anywhere near them. Then add a signalling system so the car can easily see if it's getting too close to the car in front. Maybe add metal rails to guide the cars, so they don't even have to worry about steering and cars going in opposite directions can't possibly hit each other. Driverless cars should be no problem at all then.
Oh wait, no, according to the RMT, the cars would then need a driver _and_ a guard.
