Nearly been involved in 2 collisions today in Lincoln Ne by what I call for lack of a better word : "left turn light jumpers". I am at an intersection with only green lights( no left turn green or yellow arrows) I am in a lane going straight ahead. across from me is a vehicle who is indicating he wants to turn left. At the very millisecond that the light turns green, the idiot jets out in front of me and I have little option short of an accident than to let him go. This happened twice today. Of course the first one had his booming stereo blasting bass at 1000000 decibels and the second guy appeared to be holding a big tablet above his steering wheel. Anyway, most any traffic manual in any state will have something to this effect about left turns and right of ways. "When turning left at an intersection with no protected left or left arrow you must yield to drivers going straight." I fail to see why that is so difficult for some people to grasp. Also at many residential intersections with no light, the concept of yielding to the right seems to be a lost art form. Most just blast through with out even a glance as if they own the roads. Of course we have several roundabouts as well in this town and I don't even want to start in on that topic, lest I get a massive migraine.People even find a way to make roundabouts difficult. Lately the left turners who think they have ROW over straight ahead traffic is what i find to be the most annoying and dangerous.
