As some one who bought into the govt push to encourage people to buy diesels in the previous decade to save money (and I did, going from a sporty V6 petrol car that got me 22-32 depending on roads/distance driven to 45-60mpg in a larger, heavier and yet more comfortable diesel saloon)... I'm wary of anything that is being pushed as the new thing to have for the environment...
Electric cars are not a solution, they don't cut emissions as they simply transfer the emissions from the exhaust pipe to the power stations. Range anxiety, slow charging and so forth are of no use to anyone who is required to travel any reasonable distance in an expected time... I'm sure employers would love to hear how your shiny new environmentally friendly vehicle took you an extra 2hrs to get to the site and begin work.. because you had to charge it up halfway there... Or for those who make multiple visits to multiple clients, often in places with no access to chargers at all.. meaning yet another stop to recharge your vehicle enough to make it to the next needed mini top up.
Fuel cells on the other hand ARE a decent and viable solution, and as a short term fix, hybrid cars should be what people are looking to purchase until such a time as govt/business gets of their arse and puts the infrastructure in place to refuel fuel cell vehicles.
All electric vehicles are a con and the intention is to convince people to BUY MORE CARS and prop up a floundering economy caused by Labours incompetence and the Tories greed and desire to punish any one who's not rich... and god help you if you are sick or disabled... because they really loathe those types and want to see them suffer more and more each day.
