I saw a guy on a bicycle a month ago screaming at the top of his lungs at cars behind him on the street.
FUCKING GO AROUND YOU PIECES OF SHIT!
to which the first car did and the man promptly kicked the fender and dented it. hilariously he almost fell off his bike but was able to balance it out.
not two feet away was a sidewalk with nary a person on it.
I live in a small city without bike lanes but the sidewalks are really nice(at least in that part of town).
some people have bad days, that's inside and outside the car. many times I don't trust what a bike rider is doing because of the above and it's impossible to see what they're doing. on the rarest of occasions do I know exactly what a rider is doing because they communicate intent very well.
I do keep a sensible distance, but when they're doing 15 on a 45 it causes a problem that requires one to go around.
I agree more bike lanes should be installed, but vindictive riders out to "prove a point" helps nobody and only serves as an example to the majority of drivers that bike riders are dangerous on the same roads as cars.
same can be said for drivers as well. many of whom should have their licenses revoked on the spot.
