"I know 311 in Chicago has a website to submit obstructions and other bike lane violations, but I have little confidence it is enforced or otherwise utilized by the city. I love bicycling and would rather not die in the process. Motorists and obstructions are the biggest danger to me and I find myself constantly having to avoid them and disrupt normal traffic in the process by leaving my dedicated lane. I'm tired of drivers parking in the bike lane when there's a dedicated parking spot nearby they could have used."
