What if a car driving a person was just a side effect, one of its on-demand purposes fulfilled.
What if you did not own a vehicle but it would be available anytime like über from close by, and when not driving you or anybody else, it will function as a receiver and giver of energy, drive to a charging station, when fully charged drive and park at a building that needs more power as a power building block. It can fulfill energy, people and object transportation needs.
It will never sit idle uselessly, just moving to where it is useful.
