I bought a camera pen in the hopes of catching some punk teenage kids who were throwing eggs and various other objects at me. There is a thread here on it. Nonetheless, the very day I put the camera on my pannier just to try it out I get mowed over. I attribute the settlement being well in the "5 figures" after all medical liens were cleared to be because of the camera. I didn't video the lady who hit me in the act, but I got every word that was spoken. I missed 2 days of work, had some road rash, bruised ribs, but still rode PBP 4 weeks later. I took the initial offer from the insurance company as well, without any haggling.
