Ride sharing and self driving are a natural combo . A ride sharing system for self driving electric cars & light trucks would be a game changer for 'last mile' and intra suburban transport ,

And ride sharing would reduce the manufacturing cost of providing a fleet of these vehicles for a city since fewer vehicles would be needed for the same number of people.

Here are several use cases where it would be ideal.

1: Transport to your residence or place of work from a mass transit station in inclement weather , or for people with heavy things to carry or the disabled who find travel to the mass transit station impractical or impossible.

The vehicle would be stationed in a parking lot/recharging station at the mass transit station and be available for rent via an app , it would then return to the parking lot autonomously and connect to the recharger to be ready for the next person. or conversely it could be summoned via the app and drive autonomously to the customer to be used .

2: An electric light truck variant could be used for moving or furniture delivery.

3: Disabled individuals could have access to accessible electric vehicles on an 'on demand' basis making trips to the stores or friends far easier for them. And stores would not need dozens of disabled parking spots or even a parking lot at all , they would only need one or two accessible general use loading and unloading areas near the entrance. and the acres and acres of land that was once a parking lot could be repurposed as a park or community space of some kind , or perhaps rezoned to provide extra housing for an over populated area.
