That's what dictates packaging as much as anything, not the space

to deform.


Nah. Twice that amount of space at least is going to be used for the
batteries.

Still seems to me like a very heavy vehicle with not much load space and
poor economics.


Pay attention, modern battery packs are not big, especially Lith
batteries.


I've never seen Lithium batteries even *remotely* close to the sort of
capacity that'd be needed for any sensible range on an electric car. What
sort of size do you think they'd be?

About the size of a shoe box?
About the size of a box of 5 reams of A4 paper?
About the size of a domestic washing machine?
