Electric cars in my opinion have a long way to go, the mileage rates are almost certainly based on a car driven without lights, no radio and all other equipment not required to make the car move turned off, up to 500 miles is probably more like 300, in the States really ? might just about be useful in the UK if your travelling from middle of country to London & traffic willing you may get back. You find you get to your job, no charging points, time is of the essence so no time to stop half way for a top up. I'm sorry but for business or long distant travelers it just does not stack up. The cost of the cars are prohibitive for many, and I bet the guarantee of 8 years on the battery pack are based on a limited number of charges, probably less than the average user. I believe the fuel cell has got to be the way to go. The bullet proofing might come in handy, but not much use in UK. I purchased a Ford Fiesta ECO Boost two years ago, the specs on up to 75 miles a gallon and zero road fund tax tempted me. Yes for a small 3 cylinder car it's quite nippy off the line (not if your a boy racer), the 75 miles per gallon ?. I took a trip that was 271 miles, I reset the MPG, drove much to the annoyance of other drivers in a manner & speed to conserve the fuel on mainly motorways without any holdups, it achieved an average of 49.7 MPG I think 75 MPG is on a flat road, wind behind & no stops. The return journey produced 49.2 (must have been a few more hills)
