I feel like I must be in a distinct minority because I personally prefer painted bike lanes over any other alternative. It's pretty rare in my own experience to have cars ignoring or being impatient with them (maybe because I like in a fairly bike-friendly city) I also don't like getting stuck behind really slow people in physically separate lanes where there's no room to pass.
We have 200 m total of segregated bike paths in my city so I don't have too much of an opinion on them.
My complaint is the feeling of being forced to use them when they are the dirtiest and most dangerous part of the road. They are just dashed white lines that were designed by someone who drove down the street in a Transit van once.
Since I've been moved to WFH I exclusively cycle on country roads, I feel like if we had more segregated bike paths in the city I wouldn't mind being stuck behind people, I feel like commuting or cycling into town is a different thing from cycling for exercise or as a sport.
I live in a country where cycling as a mode of transport is basically non-existent, 95% of the people I see on bikes are on road bikes and wearing lycra, so it's possible I'd feel differently about segregated lanes if there more of a cycling-as-transport culture here.
My issue is that painted bike lanes are also de facto loading, waiting, and short term parking zones. The bike lane existing makes car drivers more hostile when I'm forced to enter "their" lane because of cars blocking mine.
Yes sure this is an enforcement issue I guess. Why not just build a physical barrier that doesn't require enforcement though.
