Your impression of Delhi and Agadir doesn't seem right to me. By the numbers, Delhi has the highest crime-rate in india, but it has a 5 times lower rate of crime than San Francisco does.

And also, self-driving cars will all have enough cameras and be constantly connected to a server that theft will be far less likely for them than regular cars... and regular calls already seem to get by just fine without people stripping them to the bolts.
