I haven't thought about this deeply, I'm thinking out loud...
What are the energy cost implications of this? Okay, I drive my car to work, and it sits there until I go home. If it was part of a fleet, it would leave my work parking lot, go to some other part of town (empty, using energy), and so on. Okay, we can also save energy by ride sharing, but I speculate that it wouldn't take much to make that really unappealing. In reality, we don't just go from home to work and back; we stop at the grocery, drop the kids off at school, and so on.
We already have fleets of automatic cars - they are called taxis. Their neural net is wet, is all. So as a first approximation I'd say taxi fleets are a pretty good proxy for energy use and cost. Sure, the driver needs to be paid, but we can model that.
