Taking this off at a slight tangent but still EV-related, many if not most families have 2 cars, one a larger "mile muncher" for going on holiday etc, and often a smaller "runaround" that never goes past the next town. Often this is a cheap, older car, but sometimes it's not, and there are often attractive offers, e.g. inclusive packages, involving newer small cars like the Ford KA and the Vauxhall Adam (the Corsa has now seen some "model inflation" and is really now what the Astra was 20 years ago).
Should consideration be given to launching cheaper, lower-range EVs only intended to go up to perhaps 40mph, and aim these at the runaround? The petrol "micro-cars" popular in France, though perhaps slightly larger to allow for 4 seats and a small boot, might be a reasonable model to look at.
Because of the smaller battery (you'd only need a range of maybe 50 miles at most) these could easily fully charge overnight off a normal 13A socket. And perhaps cheaper battery tech could be used.
Clearly manufacturers are mostly favouring larger, more expensive cars as they are more profitable, a bit like housebuilders like 4-bed detached houses. But could the Government provide incentives?
