A few years ago I spent a day driving in central London in a Ford Think, which was Uncle Henry’s attempt to create an all-electric car for the urban market.

It was one of the most horrible experiences of my motoring life. For all the millions that Ford had ploughed into the creation of the two-seat Think City, it felt horribly out of its depth when asked to deal with the capital’s traffic. The unassisted steering was heavy, rear visibility was terrible and the chassis crashed its way through every pothole as a couple of hundred kilos of batteries made their presence felt.

The worst bit was the fact that, after making less than 10 miles of very slow progress across London, the battery gauge reported that it had less than half charge remaining, meaning that getting back required the use of an AA transporter.

Ford’s accountants subsequently worked out that the project wouldn’t be economically viable even if the Think wore a £15,000 price tag and – to nobody’s surprise – the whole project was wound down a few months later.
