I never said anything about behavior, only about accidents and the results thereof. I'd really really rather get hit by a cyclist at any speed than a much heavier vehicle, that's just basic physics. And your examples are just that: examples (possibly exaggerated or factually incorrect ones, re: the 50km/h on sidewalk - it's really hard for humans to correctly judge speed). Anyway: examples which I also see from time to time, but I'm well aware of things like confirmation bias so without any actual hard numbers nor specifying more variables, it's quite hard to say 'x does y on average'. That being said, I do have the impression in the local town (but definitely not everywhere) the behavior of cyclists in general became worse in the last decades. I'd really wish I had a way to make sure, but I just don't remember seeing multiple highest category rule violations every single day.
