I was reading an article on EV in the States. I can't remember which State it was, but the author of the article mentioned in his cost breakdown, that there was a yearly tax on the EV 'for not using petrol/diesel'!
The way it brokedown, was that it actually cost more to run the EV than the traditional 'ICE' car. That being said, he gave the cost of fuel as $2.80/gal - now, if you convert what we/most of Europe pay for fuel, it'd be around $7.50/gal - that would change the balance to the EVs favour!!
