As a Belgian, that is heavily involved in alternative mobility advocacy, I can tell you, everyone everywhere complains about the behavior of road users in their city.

NYC, LA, Houston, Toronto, London, Paris, Barcelona, Milan, ... Heck, even in my small Belgian city with a 100k population people think we have the worst road users.

Cars complain about cyclists. Cyclists complain about cars. Everywhere.

Studies (both in the EU and the US) that look at how often both drivers and cyclists break the law consistently find that they break the law at the same rate. Being a driver or a cyclist doesn't make one more prone to breaking the law. It's all just confirmation bias.

Turns out, it's just assholes being assholes. Someone who breaks the law while driving isn't going to magically behave when on a bicycle. And vice versa.

The Dutch realized this many decades ago already. So they decided to apply the logic "if people are going to break the law anyway, it's best if they're on a bicycle, not in a car".

After all, a cyclist breaking the law and hitting a pedestrian is bad. But the pedestrian likely lives to rant about it.
But a car driver breaking the law and hitting a pedestrian? High likelihood that pedestrian doesn't live to tell the tale.

The solution is to formalize accommodations for motorized micro-mobility. Scooters and ebikes and mopeds exist, and they are very well-adapted for city travel, so we need to give them designated street space if mixing them with other traffic is dangerous.
