I'd be more concerned about that HGV overtaking like that
I'd like to know the location / speed of road / speed dashcam driver was travelling at before I make any further assumptions but looking at the road markings and the junction (coming into view at 45secs) it looks to me a very dangerous overtake by HGV
Stupid driving. But I guarantee you this. If you reported this to the police then your use of rude hand gestures would work against you, as the police would see is provocation. Don't do it mate..be the bigger person. Don't give an idiot driver even more reason to try and wriggle out of an offense.
You control the gap at the front of your own car. In this clip it's clear that you slowed down to antagonise the driver behind. Sounding your horn and gesticulating to another driver to slow down moving away from you - which rule is that from?
Seems to me you're as bad as each other in this clip. Calm down.
