I noticed this tosser being a tosser about getting out of and back into the left lane and gave him plenty of space as he clearly wasn't paying attention. He pulled into the queue at the lights, which then changed. The 10 or so cars in front did not move quickly enough for him, as he began to beep his horn. He was about 4 foot from the van in front and rather than wait for that van to move accelerated and just kept going right up to the tail of the van. I was just behind thinking 'tosser, I hate it when people sit right on my tail.' And then, to my surprise, he just drove into the back of the van. He didn't even try and stop, he just drove into it. Maybe he just wasn't paying attention but it looked like he just drove into him
I considered stopping to advise van driver that the guy had just driven into the back of him without even trying to stop, but decided I couldn't be bothered to get involved, probably should've done though.
Other thing that really pisses me off at the moment is loud things on the road. Cycling behind a cyclist who rang his bell every time something moved, even if it was just a pedestrian innocently walking along the pavement. And also, those crappy loud-exhaust motorbikes that seem to infest North London. Ohhh they piss me off.
