Just a few days ago, I came up to a set of lights. There was one for going straight, and one for turning left. I am very familliar and know the lights going left are very slow and don't turn green very often, or very long. So, straight it is for me. When I came up ther, there were a few cars in both lanes. Then one guy decides that he doesn't want to go straight, but left. He was the last car for both lines, so he starts to wiggle into the lane for left, but there was no way he could make a turn that short, so he decided to just block the lane for straight ahead, when that light turned green, forcing everyone behind him (first me, then at least 5 more) to wait until the other light turned green as well, and like I said, that light is never in any fucking hurry.
Another set of lights: One lane for going left, straight and right, fairly typical. I wasn't at the lights yet, but I couldn't see any cars from the other three directions, so I was sort of counting on them turning green. There was one car in the lane for going left. I made my approach at 80, which was the legal speed limit, and right on cue, both our lights turned green. Then, The guy in front out of nowhere pulls out to the right, gunning it as hard as he can to go straight ahead, no indicators or anything. I nearly rear-ended him because he didn't look in his mirrors.
There are also the usual annoyances, trucks and caravannists overtaking, people going 100 in the middle lane on the highway, not indicating when they are about to leave a roundabout (my biggest annoyance), yobbos using the Autobahn as a racetrack because ''it doesn't have a speedlimit ergo racing is allowed'' (I should probably stress this will cost you your license in Germany, if not your life) and of course, people who think texting is so important, it absolutely can't wait until you are at their destination.
