Its a hard problem, but LIDAR has similar issues. Snow can cause noise for other sensors as well. In each case it seems like these issues are not insurmountable

Its a hard problem, but LIDAR has similar issues. Snow can cause noise for other sensors as well. In each case it seems like these issues are not insurmountable. I don't expect that any self-driving systems will start out with handling all weather conditions. Even in the long term they may handle fewer conditions than humans.
