A car takes up the same space whether it's LPG, Petrol, Diesel or Electric. The first three are refuelled in a short space of time but that's not so for Electric. That means there's more occupied spaces? However, I can see less need for "Recharging Stations" (as against petrol stations) as such because there ought to be many more places from which to charge an EV.

I don't see any progression towards making the roof, bonnet or boot from solar panels or incorporating air ducts to drive some sort of fan(s) to help keep the batteries charged?

Batteries don't last forever and sometimes an ageing  battery can be fine today but dead tomorrow so the EV batteries should have some sort of warning of imminent failure?
