Workstand - I agree, I've thought about getting a helmet cam to film mad descents on long rides. I've spent plenty of time watching people get up and down famous hills on Youtube, before having a go at the myself. I probably wouldn't use it to film myself telling someone off for running a red light though, or if a car cut me up. I'd just take my normal approach of making an OTT gesticulation, being a bit annoyed for a minute then forgetting about it and carrying on with my day.
