Some really good posts here.
Amazed at the vitriol directed towards cyclists, mainly for the reasons that Poppet45 mentioned.
However, as someone else said, I can imagine that cyclists in London are a whole different story. I was also shocked at the aggression from cyclists when I visited Cambridge a couple of years back.
WhatTheWhat: so sorry about what you went through there. Looks like the bully driver was just out to pick on someone? What a nightmare!
Agree that it is really dangerous to hug the kerb.
And I'd say avoid the temptation to undertake unless traffic completely stationary (like in queue for traffic lights). I must admit I do undertake a stationary queue sometimes, but I 'dribble' along rather than cycle. Or I get off and walk along the pavement (you're not going to lose any time, anyway! the traffic has stopped!!)
DH cycles everywhere. Almost. And when I first met him, I thought he was a bit of an aggressive cyclist. Almost fool-hardy. He does skip the odd red light, and it really annoys me. However, I do understand his reasoning for doing so. And as others have said, I think that in general, it probably keeps him safer at times.
And despite haveing cycled all my adult life, in various different towns and cities, I have learnt a lot since meeting him and cycling with him.
I'd say you have to be assertive, rather than aggressive. And you are safer this way.
Do make sure you're at the front of a queue at traffic lights, as this means you won't get squeezed over into the kerb by cars racing off when the lights change.
Don't hug the kerb.
Don't be afraid to pull out into the road at bit more at times (as long as it's safe behind), especially going round blind corners.
Remember that you have every right to be on the road, too.
As Poppet45 said, if someone bleats on about not paying road tax, ask them if they'd mind paying a bit more towards the NHS for their increased risk of heart disease/obesity related diseases etc
