Taxi trouble

Another day on the bike to and from the office, another day that I nearly get knocked down by a taxi.
Taxi drivers are famously poor drivers in denial, but the problem with that is that at the wheel, they become potential killers.
I have lived in London for over eight years, nearly four of them using my bike (one or other, as they all get stolen in the end...), and in all this time as a very, very careful and respectul cyclist, I have gotten knocked down quite a few times, most of them, by taxis.
Yeah, they are all of the same sort wherever you go, but here in London it's much worse than I have experienced anywhere. They are fucking wankers at best, murderers and rapists on bail at worst.
I'm so fed up with letters on the newspapers putting cyclists at the centre of trouble... we are the weakest link in the traffic chain and it is in our best interest to be careful.
A bit of respect from other drivers is only reasonable, but taxi drivers... they've only got one thing in their heads: their assholes.
