Going to bring this back on topic with some figures that seem to speak for themselves.
This chap has had a Nissan Leaf for 5 years now and has worked out the fuel cost savings and they are huge.
In 5 years he has done 51000 miles in the Leaf and it cost him $870 in electricity.
The same mileage in a petrol vehicle would have cost around $11600
Now give or take for electricity and fuel cost variation from country to country, and engine size, whichever way you look at this the money savings do speak for themselves.
I will gladly listen to anyone who can poo poo this with fact, but please don't poo poo it with poo poo.
