   Better still, standardised voltage and standardised packs where a small   
   town car may use one, while a larger, longer range car may use two or   
   three. Make the packs so they can be slid in or out - it doesn't matter   
   if each car puts them in at different locations, in different directions   
   or around different obstructions - and "battery stations" could use   
   robot arms, pre-programmed for all different models, to swap out   
   discharged batteries for fully charged ones. The service paid for at a   
   fixed sum, plus a rate for the increase in charge level.   
      
   That makes recharging an electric vehicle as fast as a petrol or diesel   
   one from the driver's point of view and ensures that failing batteries   
   are removed from circulation, with the cost spread amongst all drivers   
   rather than an individual being hit by a high fee.   
      
   It would also mean that as battery technology improved, all cars would   
   benefit, not just the latest model.
