What I want to know is, if it's caught on dashcam like you say, then why haven't you uploaded the video so we can judge for ourselves on what happened? A still picture of a car (not even in the act of committing the offence you are describing) is absolutely pointless...
The other driver wasn’t using their mirrors either , buffoon brain.
