"Parkless" cars. You own it, it drops you off and picks you up at work, and spends the rest of the time at your house.
Personal local delivery. Your car drives to a lot next to a grocery/department/whatever store. A grocery clerk walks to your car, presses a button on a smartphone app, and loads up your car with your online purchases then your car drives itself home.
Same as above except your car/truck is rented out for overnight local deliveries / short-distance freight hauling while you sleep.
Use of sensor streams from driverless cars for surveillance, mapping, etc.
Installing high-speed municipal wireless data or cellular infrastructure on fleets of roving cars without the necessity of securing right-of-way for fixed structures or ground data lines (e.g. using microwave or open air laser comms for high-bandwidth links to aerial drone stations which then eventually link down to base stations or just form a completely wireless mesh across an entire country/continent).
