Also remember that for much of the year in the UK a car will need
cabin heating. This comes for 'free' on an IC engined car - but
not on an electric one.

Renault, etc have developed insulated bodies.

Gosh, and double-glazing, too? Do tell, drivel, we are keen to know.

Actually that's the way to make electric cars work as far as heating
goes. Doesn't help in hot sun mind you..aircon...

Insluation works well for heating and cooling. Advanced glass can relect
heat back from the car.

Nope. The problem is that cars need a lot of energy, and energy
storage from batteries doesn't cut the mustard.

It does in town & city driving. Only in long hauls would a range extender
cut in.
