I commute in NYC almost every day. Some days the smile doesn't leave my face for even an instant. But unfortunately there are those other days, when I run into some combination of close calls, road rage, or a total disregard for human life. I used to race motorcycles and don't mind being close to vehicles, so long as it's done safely. What gets me is when people drive like they have blinders on, refuse to take responsibility for any of their actions on the road, and authorities pay no mind or do likewise.
I'm not trying to paint with a broad brush. I've had positive experiences with truckers, car drivers, cops, and others. And hey, I am not perfect either. I can also understand that sometimes someone might do mess up genuinely by accident as a complete anomaly and even if it endangers me, I can't really blame them -- we're all human. No, those kinds of things aren't what I'm talking about. I'm talking about people willfully behaving negligently or with malice to those around them.
There was a thread about an example of this today. I've had similar experiences. I'm fed up. I do not want to key their cars, get into fights, scare them, or antagonize them. I want to hold them accountable. I am thinking about getting a helmet cam or perhaps something mounted on the bike. Have others here had positive experiences using cameras as either leverage in the road dispute on the spot or as evidence that gets submitted to authorities and leaves a paper trail?
