I'll offer some industry partner advice.

It's already been done (since the 1950's)

The only use case that makes sense is NYC or London or Hanoi or Tokyo levels of density where the middle class is priced out by design of the car markets. Those cities cost a fortune to drive a POV. Stack these up 4 to a spot and rent them by the minute like a Bird ebike. Drop it off a few miles down the road and walk away for the next user to have it. That is the difference between then and now. With real time 5G data and GPS the tracking, rental and return of an asset is as easy as scan a qr code it opens and starts,.drive the three miles you could’ve walked in the rain and scan the code again to return it. The app and data links are the secret sauce. Ebikes & Escooters are everywhere and so easy to use. The younger generations use them natively now it would be an embarrassment to not know how to use a Uber or Bird.
