Who said these vehicles had to be land-based? If the ground's contaminated, you want to be a good few hundred feet above it. And you can do so with the Pal-V Liberty - an incredible two-seat flying machine propelled through the sky by a pair of Rotax engines.
The top speed is 112 miles per hour in the air, so it'll get you from A to B very quickly and you won't have to worry about broken roads at all. Need one? Prices start at $399,000, or around £313,500.
