Driverless cars could navigate with ground-penetrating radar.

The laser and optical sensors they currently use can become confused by snow, fog or reflections from the road. So Byron Stanley and his colleagues at the Massachusetts Institute of Technology have filed a patent for a system that uses ground-penetrating radar mounted under the car to work out its position – down to its place within a lane. It does this by comparing the distinctive pattern of cables and pipes beneath the road with survey data.
