On a more serious note, I too am thinking of a simple, cheap camera.
Not for setting up my own channel and turning into Shouty-Camera-McMessiah on acid.
More because I've seen too many troublingly close passes on my beloved children, whom I follow on training rides.
This is out on fast A Roads (A438, A417, A449, A40 etc) where pantechnicon and artic drivers seem sometimes to forget the length of their vehicle and so swing in perilously early after a pass...
Or they simply pass very, very close - which can be unnerving at high speed.
I'm not decided yet on whether to get one, but it's starting to nag at me that there may come a time when I'd like to present some footage to the local Heddlu.
I hope there isn't, but with age comes a level of fear and apprehension that was foreign to me in my youth.
