A lot of the reason I've put off buying a bike is that most of the bike lanes were either nonexistent or painted ones that abruptly ended whenever there's an intersection. I personally knew a little kid who got hit riding through the neighborhood, and whoever hit him sped off. Luckily he survived, but he very easily could have died if they hit him at a higher speed. Drivers just normalize being impatient way too much nowadays (especially after the pandemic) that you can't trust people to obey things like painted lines. You need barriers, even if they're cheap temporary solutions.
