North side of London Bridge - one lane has turned into two lanes for left and right turning traffic. Private vehicles have to wait to the last few hundred feet before moving into the left turn lane because it was a bus lane before that. Ahead of me is a car indicating to pull into the lefthand lane. I slow down and allow it to move in in front of me. A cyclist appears alongside me and promptly starts squeezing through the narrowing gap as the car pulls in front of me. He then starts giving the driver grief for "getting in his way" - it is mostly gesticulating - before disappearing up the right hand lane. The cyclist then promptly jumps the red lights. What part of this cretin's brain cells thinks that a car legitimately and safely pulling into another lane is bad but a cyclist jumping lights is not. No wonder motorists get p1ssed off with us when they have to put up with moronic behaviour from idiots like this.
