Is it true that you could in theory change batteries as fast as they can fill a petrol bike with petrol Mugen ?? , I believe one of the teams said they could ,

As a side question if all personal transport was turned over to Electric propulsion at what time of night would we all have to switch everything off in the hone to allow all the vehicles to be charged up , just a thought ?
and when all the oil has gone and we are all using these wonderfull machines what are we using to power the hgv's to deliver every thing we need to feed our selves every thing we need to build these wonder full machines to power the ships we need to ship things around the world ?? Some how I just don't see Electricity being the answer
But then it's only me
