>This cyclist was pretty fast, as fast as the rest of the traffic, so can, should and usually would, be treated just like a car driver
Indeedy ! - or even more akin to a motorcyclist...
(plus all the rest)
I generally agree with the points re winding up drivers, but the problem's ignorance/prejudice - the only way you'd keep some people happy is to not be on the road at all.
Other thing to add re filtering - it's a long queue, there *will* be a gap somewhere - probably better seen by the rider than on the cam. - and in any case, you only need enough to tuck the bike into to avoid oncoming traffic (ditto if I were on a motorcycle). Plus by the time you allow for general driver doziness on pulling away, any gap that's there gets bigger as the traffic ahead starts moving. If you like, if you do push into a gap, you can always wave a 'thanks' after you've pulled across if you feel you're taking the mick. Taken to extremes - if you're not prepared to filter in significantly stationary traffic - then you may as well get in a box with the rest of 'em...
I should add that it doesn't mean I'll filter every last place in a traffic queue, it depends on the situation on - but drivers have to recognise that overtaking works both ways, it just needs to be done safely.
