I've always suspected that you could do something interesting with a moderate density apartment complex where renting the apartment comes with the ability to use any of the X vehicles the complex owns.

It would be some bit of legal/liability wrangling and maybe some accounting to do it, but imagine if you had 50 families in a building, and ten vehicles available ranging from a small car to a pickup truck to a van to a moving truck. Tune it a bit and there you go!
