It might depend on your location and the state of local government. I am a big proponent of taking civil action, but 1 complaint a day might be more effort than it's worth.
At least in Toronto, Canada, resident cyclist complaints got some progress over 10 years:
- First city council put in a line near the curb representing a bike lane, drivers ignored them and many parked in them.
- Then they painted some of them green and enforced it a little better. Fewer parked but many drivers still ignored it and travelled on them.
- Then they added thin bendable bollards to separate the bike lane and road. Due to shitty design, they got permanently flattened by garbage trucks making them appear like road debris.
- Finally they replaced the bollards with a better design, added more reflectors on the road and added concrete blocks/a curb in a couple downtown areas which finally achieved separation.
It's still kind of stressful for a cyclist to get around on the roads here, but improvements have been made, in part thanks to cyclist complaints. Don't lose all hope!
