Oh, right, exchangeable batteries, that'll work
The Average Briton can barely cope with fuel pumps. How are they going to deal with swapping batteries? I include service station mongs as Average Britons there.
Automated swapping? Right, have you seen how often automated car washes are closed for maintenance>
How are you going to charge (money) based on usage? Or are you going to bill fixed price for every battery swap, even if it's still half full?
Once you get above the size of a clown car, you'll need multiple batteries. How does that work?
And what happens when you inevitably get a duff battery put in and whine to a halt in the arse end of nowhere?
Electric cars are just a huge set of problems, none of which solve anything.
