I can foresee all major roads with overhead cables, so you drive on battery power from home to the main road & hookup to the overhead,like a tram & drive your car wherever, charging your batteries wherever you go. You will buy the current as you now buy gas or electricity by direct debit. Your car will be controlled by computer & auto driven so as to make all RTAs a thing of the past. Cars will be 2 seaters only & family will use fast transit trams which will be used on special built tracks to separate from other traffic. Electricity will be generated in new plants from differing methods including Solar Panels.
