&quot;Ford said it had instead programmed the Lidar sensors to detect landmarks above the ground, such as buildings and road signs.&quot;<p>So, in order to work, it needs a mapped area.  They skipped the actual problems with driving in snowy conditions.  I guess I&#x27;ll have to wait a while longer for an actual solution.  At least the didn&#x27;t go the full GPS route since I&#x27;ve been on roads that are marked 10 yards away from their actual location.
