I only commute by bike in Paris, France. The infrastructure has so much improved that if the city continues to protect bikes and pedestrians, there will be a point where I don't care if drivers aren't attentive (thanks to protected bike lanes everywhere, larger sidewalks, car max speed soon limited to 30 km/h on all streets, Idaho stop for bikes at almost all traffic lights, car ban in some districts on Sundays, no more "send uniques" for bikes, better signs, camera and speed traps, "coronapistes" that duplicate the subway map, etc).
I generalize but infrastrucures changes everything to a point where a city can easily get rid off car (give us a few years...). It's all infra since that's the only thing that changed here in the past decade: we finally dare to bike now, only because it's protected enough we don'fear for our life every few meters nowadays. For this reason, biking has become the default for most of my friends and colleagues. And the last few who haven't swichted are either taking the metro/RER or walking. The last drivers are professionals (who need to move heavy things and the infra does not support electric cargo bikes yet), old and fuck-you-momey rich boomers who still see biking as being weak, some families (who can afford to still live in Paris?!) but same issue as cargo bikes, and lost tourists (why the hell do huuuge tourist buses are allowed in so dense blocks?!).
