Jacob, i am in precisely the same mindset as you. The bike is the only way for me to get to work, in the past week i have had too many near misses. I do not think any of these could have been avoided by myself: two were cars pulling out from a side road (on the right hand side of the road) - i have a front light on blink even on day time commutes, the road is straight, visibility clear. The last time i was following traffic going about 20mph, i left a 4m gap between me and the car in front and maintained primary position on the road, car behind wanted my position overtook and forced me into the gutter, i was tapping on the side of the car to try and alert them. They ignored me and forced there position and once in front kept tapping the brakes to try and force me to crash. The first two occasions i can accept, the drivers stopped, apologised and i think the incidents gave them hell of a shock. The last incident, the women should not be on the road. A camera would have recorded and supported a case against her should the cps wanted to pursue it.
Most importantly to me is my wife and two children. If/when i am hit, i want to ensure that any compo is given as quickly as possible to reduce the impact on my family (assuming i am not dead). I do everything in my power to ride safe, be seen, i obey traffic laws, i defend my position. Bit as we see and hear everyday, insurance companies and drivers will not admit guilt unless presented with un refutable evidence, which i hope video footage will be (or at least support).
