My worst nightmare is a future where self driving cars become geolocked from areas for whatever reason.

'I'm sorry Dave, I can do that. You don't need to be in the neighborhood where the protest/strike is happening/drugs or other illegal things are sold/xyz reason, and police have geolocked the area from entry for the good of the public'.

That will give so much power to the ruling class. I intend to keep a non-self driving car as long as possible.
