I'm sorry you went through that MitziK and I'm glad you're fine now. It happened to a friend of mine, she was on a motorbike wearing shorts. She survived but has massive scars. To me and I think many others, bicycling seems less dangerous but maybe it isn't.
God, no it isn't. From my point of view, at least I had the power with which to get out of a lot of situations - like HGVs who obviously hadn't noticed I was there or car drivers pulling out of junctions as I was already crossing with right of way (quick blip and you're past/out of the way, rather than watching them in slow motion as they head towards you).
The only times I was hurt, I wasn't going any faster than a pushbike and, as I mentioned, was absolutely stationary at one point. What saved me was the protective gear. The type that is perhaps associated unfairly with being masculine. If not being permanently maimed is a masculine trait.
I now (occasionally) use a slightly different mode of transport. It's got four legs and can become hysterical at the slightest sign of change (OH MY GOD THERE'S A LEAF ON THAT TREE! RUN! FLEE!), but I don't do that in a skirt, either.
In terms of transport on two wheels, though, fuck wearing skirts and little shoes. The fundamental laws of physics don't give a shit about gender conformation and sudden decelerations, rotational speed and friction are far more important considerations than liking the feeling of the breeze up one's thighs or having a lovely picture in your head of how pretty it looks. I am not trying to be a dick for the sake of it, I think it's that important for people to get a grip and look at what they are actually putting themselves at risk of through an aesthetic choice of clothing.
