After reading a few incidents where a cager has caused someone to come off / damage their bike I was wondering if anyone uses a video camera when riding through traffic (short trips / commuting)? I know typically bike mounted cameras are used to film yourself going through the twisties. But I was thinking they could also be used to capture video footage of traffic around you. Should a cager cause you to come off the bike and it was their fault then the video could be used as evidence. Assuming it was the cager's fault and you got it on video of course. Any thoughts on this?
