If it were economically practical over the planned span of my ownership - Yes I would buy an electric car.
If it fails to make economic sense for me then -No I wouldn't buy one.
The same with Hydrogen or E85- it has to make economic sense for ME in my circumstances. I am obviously not a Faddist when it comes to my cars.
I can't save the Earth from my place on it and I can't influence trends enough to make much difference from here either. So I will do what I can towards conservation of Mothers resources without giving up my life to do so. Caves are damp and cold and drafty! Dark too!
