If Uber is right about it's autonomous taxis, and Tesla's cars really will be able to come when you whistle, then last mile driving and docking are surely solvable problems.

I'm generally an optimistic person, but I think autonomous driving is going to seriously disrupt our societies. I simply cannot see where the huge workforce of unskilled males driving trucks and taxis is going to be soaked up. The industrial revolution did it last time, but anything you can suggest as a potential equivalent (colonising Mars?) will be demanding smart flexible people - and an awful lot of automated systems.

I'm picking the mass unemployment will lead to civil war in the US (where all those unskilled males have semi automatic guns) and universal basic incomes in more civilised countries.
