“tried a driverless car in the U.S. they found that the dividing lines and road markings”
You don’t need that stuff. I’m being serious. You can determine your lane by sampling the textures in front of the vehicle to determine what constitutes ‘road’ and restrict a vehicle to remain in an area that would be determined to be a lane. Moreover, it can sample other vehicles on the road and determine that safe area as well.
Anyone who develops any kind of intelligence system that relies on painted road markers to remain safe should not be allowed to develop such a system :-). I mean, what happens when there is a dust storm or snow storm! :-).
Smoke from fires, heading directly into the sun with a pitted windshield, bug covered windshield, construction zones, detours, multi veh. wrecks in progress, Trucks blowing out tires just in front of you in the other lane, etc.
