Today I was riding ~3 feet out from parked cars (dooring is the most common way to get killed) and this pickup truck comes up behind me and just lays on its horn for an entire block. The driver was also revving his engine and coming within a foot or two of my back wheel.
The driver intentionally cut me off forcing me to swerve to avoid the back of their truck. As he passed me the passenger rolled down his window and informed me (using very crude language) that I should get off the road.
I have had three or four incidents like this in the last year and I am getting increasingly infuriated by them. They have all been on residential streets that drivers are using to avoid the city's arteries. I do my best to be courteous and don't accept this behaviour.
I think that I need to do something so that I don't end up throwing my bike through someone's windshield doing something inappropriate.
I have been considering getting a camera on my bike but wonder if this would be useful.
Question: Has anyone ever contacted their local police regarding aggressive drivers? Were the police helpful? Would video evidence be useful? (I suspect that a camera would help to remember an aggressive driver's information even if video evidence was not required by the police).
Question: In the case of an accident would video evidence be useful to press criminal charges against a driver? If I am injured would video evidence be useful if I wanted to seek damages in civil court?
I live in Ontario, Canada.
