I ride to work and also take a long way around to avoid most of the roads. I think I'll be installing a camera though. In Brisbane a lot of people just seem to hate all cyclists, no matter what they're doing. People will swing into bike lanes just to mess with you, they'll overtake you in a one lane roundabout even if you're doing 60km/hr and they yell abuse at you, even when you're standing with your bike at the side of the road.
I try to ride safely and within the road rules at all times. I don't wear lycra or ride in a peloton and my bike is lit up with expensive lights and reflective material. Even so, to a lot of drivers I'm just an arrogant pig who deserves to die.
So, if someone does run me down, the camera will give a good indication of what happened. My GPS unit will also record the speed, direction, location and so on. It will make it easier to sort out the insurance claim and, if necessary, assist any prosecution.
