Here comes the rant....
I'm so sick of articles like this one. At no point are the individual circumstances looked at (someone else did and concluded it could well be a statistical anomaly). I am of this opinion as several of the women killed were, by all accounts, confident and competent cyclists happy to take the lane.
Anyhoo, I can only think of my personal experiences when it comes to women cycling:
It seems to be true that most of the women I know (I include myself) are less spatially aware, but actually this, in my experience, means that we avoid nipping through narrow spaces as we're worried we're too wide. It therefore doesn't make any sense that it would mean we're more likely to squeeze up the left-hand side of a lorry.
As a woman, it's often assumed I'm going to be slower, I know this because I get left-hooked far more than my male cyclist friends and I often have male cyclists plant themselves in front of me at lights even though I've overtaken them before. I aint that quick, but at 15-20mph on my commute my speed is often commented on, it isn't when it's a man riding.
Men often attempt to force me up the insides of lorries. Three cyclists have hit me from behind because I've hung back behind a heavy vehicle that I haven't wanted to undertake. I've been sworn and tutted at. I don't care but I've seen other women feel like they have to move, even if it's dangerous, all to shave precious seconds off their 5-mile odyssey.
And finally... Most women I know are more easily intimidated by drivers than men. I cycle where I feel safe, and sometimes it's the centre of the lane. I'm happy to shout the odds with drivers who take exception, but more than a few women I know are upset or frightened by this kind of encounter. They are also more likely to assume it was their fault. This explains a lot of the kerb-hugging behaviour I see when out and about. Kerb-hugging leads to people being in the wrong lane when they hit a junction, generally the left-turn lane when they want to turn right or go straight ahead.
