As for introducing their electric car range, good luck to them but I can't see them working out for people. How many Nissan Leafs do you see on the road? Not many. And they take forever to recharge, not handy for long distance journeys really. If you're on a business trip and your car runs out of electric before you arrive, are you supposed to phone your client and say "Sorry, my car has ran out of electric! We'll have to wait until its charged tomorrow" and sit in the service station for the rest of the day.
The technology isn't quite there yet and there still needs to be more R&D into it. Until you can get an electric car that will recharge its battery as quickly as you or I top up with petrol, and an electric car that won't need a new battery every year, I can't see it hitting off.
