The bang you hear at 1.38 is the van smacking into my elbow, I was really injured and couldn't drive for weeks!
The consensus seems to be growing that this is a fib. I've looked at the video and it smells more and more like the cyclist slapping the van.
Did the OP slap the van and cause an injury that meant four weeks off work?
Some lessons in van slapping required, if so. And maybe a lesson in making honest claims.
The driving by the motorist was dreadful and his violent response inexcusable.
Posting legalistic piffle at the end of the clip about what is required under law after an RTC is shameful and humiliating for the poor, deluded OP if (as seems to be the consensus) the 'RTC' was him slapping the van. I imagine that the OP might stay off CC for a while after this apparent lie and the horse-poo thread about an MGIF at a mini-roundabout. Poor roadcraft and a loose relationship with the truth... Ooops!
The lies were shabby and cheap, to put it in the best light I can. It is inexcusably uncivilised and cowardly to post footage complaining about the behaviour of others that contains what looks increasingly like a lie. The van driver is no better; perhaps worse.
