I can envision this being semi feasible with electric cars.
Maybe not with street parking, but some kind of standardized wheelbase to charger dimensions, and some lifts/carousels. Charge and maybe more efficient parking too.
Drive in, get out, machine clamps up, plugs up, and then lifts the car vertical and turns to the next slot. It’d be fun to watch anyway. Like a round Vert-a-pac.
Probably some mechanical reason electric vehicles can’t be vertical that I don’t know about though.















Yep. Great point.
Sci-fi power density required.
