Without my helmet cam footage, the Met would have never got a case together against the guy who drove his car in to me.
I also have no problem using footage to grass on mobile phone using drivers , I don't want to be hit by one of those idiots.
I look at the footage for about 5 mins when I get home some evenings IF something I didn't like happened but I rarely get to the point where I'm editing it and posting it to YouTube or something. The most time it takes up of my day is recharging it and deleting the files but I'd feel vulnerable if I didn't use it.
