Germans are usually pretty good at obeying the highway code equivalent, except cyclists who frequently don't bother to put their lights on, one of my pet hates. I've had one or two near misses when I've only seen someone at the last minute.
Tuesday morning, discovered on the way to work my front light wasn't working, so I would have to ride home with only the back light. Started out, was overtaken by a cyclist with the front light working but back light broken. Followed him, caught him up in the next town and told him, turns out to be colleague I know who lives in the same village. So we did the rest of the trip with him providing the front light and me providing the rear light!
