I cringe when I see stuff like this.
Partly because the cyclist clearly thought it was worthy of posting on Youtube... Why are some people so deeply unaware of how daft they look? I have the impression that this wasn't posted in some sort of humorous mood.
Partly also because a certain breed of fellow cyclist (fellow traveller?) finds something noble, just and heroic in this sort of masturbatory 'vigilante of smugness' wrongheadedness and puts the link up in fora like this....
There is something about some people that simply forces them to mug their heads off when they know they are being filmed (by themselves). The turnip in this clip is not unlike the goons who gurn behind OB takes on the News at Ten... apart from the fact that those guys know they look absurd and this chap thinks he's some sort of Captain Headcam, Hero of the A735 (and one or two minor roads he might find himself on when traffic conditions are suitable).
WHen I was a motorcycle courier (really, I was, I just never talk about it) one of our chaps was a bit of a racer and seeing a white, faired BMW in his vibrating mirrors, he gave it the beans on his RD350LC. Some miles later he observed the blue lights on this white Bimmer and pulled over. It was 1984. The first words from the police motorcyclist were "Have you always been a c**t?" It became folklore at my courier firm and the rider himself dined out on it...
How I wish regulations still allowed police officers to speak that way...
