Your forgeting one thing,
As the majority of cars are still gas powered, think how many jobs will go bust if we use electric,
Petrol attendants, garages, spares shops,the list goes on and on.
Also the goverment will have to find a way to tax them, cant use a fuel levy and electricity is a bit of a hit and miss affair,
Thats why the EV1 sold in the us was crushed becuse too many unknowns that yet to be worked out.....
