That's a brilliant solution to the problem for cars that aren't Teslas, which has something like 1800 batteries lining its cabin floor. I don't think they'd be easily swapped.

For cars that don't implement batteries this way, I'm wondering how they allow for non-floor-mounted installations preventing the batteries from destroying their handling.

Further, how are the filling stations expected to deal with the variety of non-standard battery types on the market?
