Glad you are ok CP shaken but not stirred. This is one of the reasons I gave up riding everyday as I had several w4nkers do this to me. Some of them even had the rudeness to give me a one fingered salute as they steamed head on toward me at speeds well in excess of 60mph on unclassified Fenland roads. Several times I jumped for my life with bike straight off the road into drainage ditches. Now I only ride occasionally at weekends as it is just too feckin' dangerous. There are a growing hardcore of motons who just do not give a sh1t about cyclists. Like you I used to wear hi-viz and have numeorus lights.
Earlier in the summer however I did invest in 2 Muvi cams, but as good as they are they are still a bit pathetic really. So recently I bought a Contour HD head cam which seems pretty good. Since I got it I have used it mainly for running as I am sick of being chased and abused by dogs and their owners some of whom are really nasty pieces of work. I wished I had it on this evening as some silly bint allowed a huge black dog to chase me, she didn't even call it back. It was twilight nearly dark so I stopped and asked if she'd like it if chased her aggressively trying to bite her which was met with the usual foul abuse. I'll try the Contour HD as a helmet cam tomorrow when I set off early to ride to Cambridge via the number one cycle hating place in the UK full of knuckle draggers - St. Ives, but then after this it is cycling nirvana all the way to Cambridge and back along the guided busway. But I wouldn't cycle on the roads again without a helmet cam as if something were to happen, video evidence would be worth many times it's weight in gold, but without which and no witnesses, having had your life seriously endangered, been forced off the road or knocked down, the police and the CPS will do feck all.
