There are several trials similar to this one taking place across the UK. In addition, there are over 1,200 electric cars being driven in London by people who have bought their own and are happily using them every day.

It does not surprise me that so many people are keen to make the switch to electric cars - they are superior in so many ways to gasoline vehicles.
The UK government have also just announced the new nationwide electric car recharging network as well, consisting of public charging points and high speed charging for major routes. It's exciting times...
