'Cyclists are dangerous. I saw one doing xxx this morning'
I know this is a difficult idea to grasp, but that person who ended up in a body bag in Aldgate wasn't the same person that you saw being an idiot on a bike in Kensington.
If cyclists are all to be judged on that one person who annoyed you this morning on your daily commute, then it seems only fair to do the same back.
Drivers are all speeding lunatics who change lanes without indicating, thrusting their un-taxed, uninsured motor around the road while talking on their mobile phones, blaring out the Radio One Breakfast Show at unbearable volumes and smoking out of the window. Oh, and you can't pass a woman without leaning out and shouting 'oi oiiii larvely! Fancy a shag?' and beeping your horn incessantly.
