"But these sensors do not work well in snowy conditions, and the car's onboard cameras cannot see road markings obscured by snow. Ford said it had instead programmed the Lidar sensors to detect landmarks above the ground, such as buildings and road signs." Countryside usually there is a lot more snow on the street and especially next to the street. Detecting "landmarks" there will be hard. Also if you combine LIDAR with stereo cameras, you will find out like Mercedes dod in the 1980s that cameras have problems with low stand sun (light rays), common in winter season (evening). So winter conditions will be harder to solve.
