So far all reports from top gear to guy Martin, itv special and Chanel 4's despatches currently all advise that electric car ownership to travel the length and breadth of the country is currently an extremely stressful and time consuming affair, and currently doesn't suit the majority of people's lives.
Add in if you heavily load the car for a family holiday the mileage drops significantly, and then added to that the degradation of the batteries in just a few years currently means that for most people with electric cars they have a 2nd car that has an ICE, with the electric car being their primary daily driver. Personally I would like an electric car to travel to and from work, and then have the family car with a petrol engine to do the job of ferrying the family up and down the country.
At present it's to early in the transition period for most to be a complete convert to electric car ownership.
