Agreed, though they're pushing the mew ones as being capable of fast long distance travel, aided by charging points at motorway services. I could go from Stoke to London in a day now by electric car, pausing en route for large meals at Hopwood Park and Warwick services while the car's batteries got topped up on the way. There may be other charging points on the way, but they're the only ones I've noticed while walking from the coach park into the service areas.
Then again, £20,000 only buys about 150,000 miles worth of petrol in a car that size at motorway speed.
