With self driving cars the govt is going to decide where you go and when you go and how fast you go. You will loose your remaining freedom. Can’t live there not allowed. It is all part of a utopian wet dream.
Let's not forget that the manufacturer ALWAYS has access to the car for "important software updates" &c. It's a given that government will use and abuse that feature as well. The same folks who bring you no-knock raids, mistaken-identity death certificates, same-name incorrect arrest warrants &c will be able to turn your car off at any time. Maybe even while it's moving.
