Ford is developing a vehicle that can tackle even the most treacherous of snowy conditions. The Detroit-based auto manufacturer claims to be the first to test fully-autonomous vehicles in winter weather. It has revealed tests that show one of its vehicles driving safely round slippery corners as a flurry of snowflakes surround it.  The car uses a combination of 3D maps and LiDar technology to ‘see’ road markings obscured by drifts of snow, while safety features like traction control help too keep it from losing control.  ‘It’s one thing for a car to drive itself in perfect weather, but it’s quite another to do so when the car’s sensors can’t see the road because it’s covered in snow, said Jim McBride, Ford technical leader for autonomous vehicles.
