Ford is getting a head start on making their autonomous cars feel at home in the snow, a condition that can be tricky for driverless vehicle systems. The winter weather coats the ground, covering up lane markers, signs and other features the cars use to navigate the road — and, of course, it's slippery, NBC News reported.
"In the real world you don't always have perfect sunny weather," said Ford's director of autonomous vehicles and controls, Randy Visintainer, in a video put out by the company.
Until now, testing has largely been done under good conditions in sunny states like California, Nevada and Texas. Google's driverless cars only recently encountered rain, and had to be outfitted with tiny wipers for their sensors.
