Thanks for the comments
Rural Lancashire is fortunate for the lack of traffic, which mostly goes to the Lake District on sunny days. I often forget how fortunate I am, as I do a fair bit of cycling too.
My Interstate does have mirrors, and I do 'check 6' regularly, as is correct for a Brit Biker

My 900ss would be utterly ruined by such things, and I'm well used to not having any. As has already been pointed out, they only need to be serviceable if actually fitted - it's the same with indicators, although on post '86 bikes they're mandatory.
Funny how it looks fast - I don't think I broke 60 for the duration as it's pretty difficult on these roads! Rural speed limit is 'derestricted', i.e. 60mph except were signposted otherwise.
The camera is a Turnigy GoPro clone which was about £80 - they've since come down to less than £40 :shock:
No complaints - seems to be a good camera, comes complete with waterproof case for the traditional British weather. Funnily enough I spent a week at Cosford last year hearing some ex-NCO BSing about aircraft design - put me right off, it did, but the Officer's Mess beer prices were some compensation :wink:
The camera perspective isn't too distorting - the legs do get in the way a tad, as I'm 6'10"
