Battery technology is improving all the time. A great deal of work is being done internationally on improving batteries. If battery technology takes a step change for the better, would the owners have to pay the full cost of the new battery set that needs to go into a vehicle? In other words, if I have a petrol or diesel engine car, the technology is changing but they are gradual changes and I will not have to change the car engine.
