I’ve always been horrified, even as a child, by the clouds of black smoke emerging from the back of vehicles, especially diesels. As a pedestrian, a cyclist, or in a car following directly in the slipstream of a diesel vehicle, you breathe in a huge volume of this filth. In Britain alone, 34,000 people a year die from inhaling exhaust fumes.
