That my other problem with them price you are paying so much more for usually a much lower spec than the petrol or diesel equivalent. Ounce or if the price comes down more people will get into them.
It's like anything new costs a fortune then a few years later people are chucking them out, not quite to that extreme with vehicles but once the second hand market for them increases they'll become more affordable. You can pick up a used electric van (berlingo size) for around 10-15k at the moment, still out of my price range by quite a bit
