> Why would either driver would try to pass the other if they are going the same speed? If they're not passing then they should move to the right out of courtesy. (And they're legally required to in some states.) And, yet, I deal with this all the time in Texas and California. I shudder at the thought of more of these kinds of people on the roads. > If the truck driver is traveling "at half the speed limit" at any point then it should be a simple matter for even the most principled drivers to pass them quickly and safely. I think you don't have much driving experience with idiots on two-lane roads. I have experienced this failure mode in California, Texas, New York, and Pennsylvania--I have no reason to believe it doesn't also fail elsewhere. It doesn't take very many cars piled up behind a truck before you do not have the ability to overtake them all while your passing zone exists. See this video for what kind of zone I am talking about (sorry that it's an annoying comedy defensive driving video): https://youtu.be/Duw-c8O8Y9Y?t=104 https://youtu.be/Duw-c8O8Y9Y?t=104 These kinds of tracking devices will make these failure modes worse, not better.
