infrastructure would need to adapt, but this is the only way i see for city dwellers to be able to adopt electrics, (i mean you could do the same in parking garages, one charger per space, they lock to the car till you pay)
payment is negotiated at the interface when plugged in.
It wouldn't be ridiculous to have a charging station that moves in a garage.
ie - services 4 cars at a time x 1 for each row x 1 for each floor -
The grid can be managed - charging rates (ampHours), priority, planned trip, amount remaining - all factors, along with current load from A/C etc.
you could even pay for priority (or lack of planning)

We are also holding onto the old model of owning a car, parking it out front, driving it, parking it.....
It is going to go to a subscription model where you either schedule, or summon a car. It will show up, and
take you someplace, then go on its way (maybe to the next ride or recharge) -
Then the parking spots will be bike lanes -
it would be the right size car for the mission too. right number of seats to keep weight down.
kid seats, room for luggage if needed, etc.
