I bike to work every day since 4/5 years, in Switzerland. Since roughly 18 months, I have seen a huge change in the behavior of car drivers: they are much much nicer to interact with. Before COVID, I had dangerous interaction with drivers several time a week, and had to be in constant vigilance for them not considering me as part of the traffic. Now, it has been reduced to maybe once a month. Sometimes I don't even believe how well people respect us now, considering how it was just 3 years ago. And most of the time when I confront people that did something dangerous, they are sorry and feel bad about it (it really wasn't like this a few years ago...)
