What you need is a car that runs on Rechargable DDDDDDDDD Cells. As they

your ejected set can be rotated into the next car that pulls in.

The GM EV1 used many AA sized cells didn't it? It becomes an ownership
issue. who's to say what the charge tretention is of the exchanged set,
what if the older battery has a higher internal resistance.

Having said that with no tax and low insurance cost a EV shopping cart would
suit my wife in the summer, trouble is capital cost is higher than a cheap
petrol engined car for the 10 or so miles she does in a day.
