> It’s funny how rare it is for people to realise the obvious - that the chargers should be in the road, not taking the little amount of public space not given to cars

Work has already started on the tech to allow this. They plan on using wireless charging. Mostly it's planned for supermarkets and what not just now, but I suspect it'll get added to standard roads over time. The main issue is getting car manufacturers to support it but they seem to be looking to add it over the next few years.
