They need that.Nobody is pretending there are no e-car disadvantages, least of all me. There are pluses and minuses for each, I just ask everyone to look at the whole picture to comment fairly.
In this respect there is an emergency top up on route for e-cars, both the AA and the RAC carry top up equipment now to get an e-car to the nearest charging point.

As I understand it, not having one, they can't be towed like ICE cars. They have to be uplifted completely if being recovered. This is hearsay - I have no experience of it myself.
