Did you know that Lightning disrupts GPS guidance. Think about it at 70 mph on a freeway. Lightning also can effect the on board computer. I never hear the industry address this absolute fact.
road glare, black ice conditions, whiteout conditions, drifts, construction, motorcycles that are dangerously weaving in and out of lanes, loss of gps signal,
I work in an industry that uses a lot of robotics.
We have multiple safety measures in place, and bots still hit racks on occasion. That is in a controlled environment, where there is little else in the cell. On an open road, a little dust and rail will mess up the sensor.
