What if I am looking away from the road to read the traffic signs, so I can know what the law is on a particular stretch or in a particular town? What if I am reading the signs of establishments so I can figure out what kinds of services are offered along the route I am traveling? Will I only have x number of seconds to look away before my car obnoxiously suggests "You are tired, pull over soon"? Driving involves a lot more than simply looking at the road. In fact you have to look away from the road constantly to evaluate your surroundings, discover where things are, read traffic signs, check your rear and side view mirrors, watch for vehicles from incoming roads to drive defensively, etc. How is an algorithm supposed to detect the difference between looking away from the road for one of the above mentioned reasons and looking away from the road because I am tired or distracted? It seems to me this technology could be extremely annoying due to false positives. Last thing I want while enjoying scenery on a road trip is some stupid algorithm suggesting to me that I'm tired when I'm wide awake.
