I appreciate that batteries degrade over time, but think this will deter many would-be EV owners. Losing 1/6 of your total range in the first 5 years of owner just doesn't happen with ICE vehicles. How long until you're down to 1/2 the original total range and can no longer handle the journeys you bought the car for? I'll probably be in the market for a new car in the next 2-3 years, and I'd very much prefer to go green next time, but this puts me off somewhat.
I wonder what the used market is going to be like too. Will many people want to buy cars that simply don't go as far as they used to (and will lose more miles as time goes on)? Do they just have to accept that a battery replacement will be necessary?
