I feel there is a lesson to be learnt for electric cars from Forklifts.
Battery changing. If charged batteries where available at depots so cars could use the battery power, pull in change a battery and continue they could be more attractive. If all electric cars used a standard battery which was as easy to change as filling up with fuel you could see them catching on. There would be a requirement for a **** of a lot of batteries, but it is a thought.
