I agree that charging seems a fair way to go but, like Roy W, and I live in a Scotland, I have never seen a charge point being abused. I went to Ballater today and occupied one of the two charge points there for a 2 hour charge (30 to 70kw) and nobody else was there for all that time. My local chargers in Banchory always seem to have at least one, and very often two, of the two chargers completely unused.
