Are electric cars improving?
Few things polarise opinion more than the electric car. It is either a great way to save the planet or a really bad way to get from A to B?
The Today programme's Evan Davis wanted to find out more, and took a ride in one with an enthusiast and a sceptic.
Bjorn Lomborg, the so-called Sceptical Environmentalist, having written a book of that name, has made a career attacking what he thinks are the irrationalities of the green movement. He is not a fan of electric cars.
Ian Hobday, who runs Liberty Electric Cars, took Evan and Mr Lomborg for a ride.
First broadcast on BBC Radio 4's Today programme on Tuesday 2 April 2013.
