Not sure EVs are going to save the environment, as others have already said. Also, whilst those who can afford to get on the train early are currently enjoying no VED and low night tariffs I suspect, as EV becomes the majority and demand increases, this will quickly change!
However, despite that I do want EV to succeed and do want one for two main reasons:
1. EVs are normally auto and that will hopefully transmit to wider choice and more level prices.
2. They are definitely better for air quality regards emissions, especially in urban built up areas.
