Aggressive cyclists

getting cut up by a bus in a big LA road is different to a red london bus pulling ahead of you and beginning to close into the kerb to stop while you're still alongside it like some fucking crash bandicoot log or something.

True, though the LA bus will be doing about 35mph, as opposed to the >10mph crawl in London. And here, the larger the vehicle, the less often the driver uses the turn signals. My last close call was with an 18-wheel artic carrying a fucking tower crane.

I think it has a lot to do with being British and our penchant for interfering and pointing out other people's misdemeanours. Basically we're busy bodies. Check the 'bad cyclists' thread if you are in any doubt.

^This, very much.

Everyone is too aggressive. English people get offended and loose their shit so easily. We need to learn the art of being happy // pushy, like the Italians.
An example of this is the use of car horns. In most of the world a beep of a horn means "hello, I'm here". If you hear it in the UK it means "I'd like you to die".

^Absolutely.
