Personally, i think driverless vehicles will only have a ltd use in the real world. Much like the 3d tv craze in 2015.
Trains, planes, large boats & ships have all been essentially driverless for decades but still need a captain at the helm to make critical descisions, and more importantly take responsibility for human life.
Driverless cars as they are currently and will be for the next 10 or 20 years are in essence a fad, simply because the computing technology is good enough now to make it work but they havent yet worked out what sort of consumer market it will generate.
I see buses and public transport going driverless, cars..yes they will have driverless features, but i do feel the majority of people will want to drive thier vehicles.
What is the point of buying a vehicle that drives itself without your input? Just think about it, loads of people all getting into thier vehicles, whilst it drives them to their job, so they can work to pay for the vehicle that drove them to work?
One thing is for sure, mental health will be an even biggger issue than it is now.
