I didn't mean buses are less safe then cars in terms of crashing, I meant in terms of hassle from the public. Have you guys seriously never experienced being on a bus or train and having some random person come and sit and talk at you incessantly even when you are clear you wish to be left alone? Even more disturbing when there's a sexual aspect and it's a man? Have you never been on a bus or train where a guy has come and sit right next to you, close enough to be touching you, and asked personal questions? If so, I'm glad for you, because it's happened several times to me and pretty much every other woman I know. It happens frequently. Not just to me, when I've been on public transport I've seen men do it to other women too.
A few weeks ago on a coach I had a horrible incident where a man tried to sit next to me, hemming me in, when there were loads of free double seats available. And when I got up to move as he wouldn't take no for an answer he physically grabbed my bags and tried to force me to sit back down so he could sit next to me.
It's all well and good saying 'nobody is interested in talking to you' as if you think I'm so big headed and full of myself I believe I'm a people magnet, but that's not what I'm saying. Being on a bus or train opens you up to having your personal space violated and worse.
Plenty of people have no choice but to get the bus anyway and I'm sure some people have never experienced it so don't even realise it happens, but the fact remains I feel much much safer in my car, alone, in control and with the ability to decide who gets in, than I do as a young woman on public transport.
