Re: Hot swapping
"Just" requires standardisation as the main hurdle.
No, that's the easy bit.
All those swapped-out batteries have to be stored somewhere they can be charged, ready to be swapped back in again. Work out how many cars a typical petrol station refuels in a 24-hour period, and then calculate how much space and electrical power you'll need to store and charge that many batteries, while venting off the surplus heat so your charging station doesn't go up in flames like an apple charger.
