You were brake-checked because you have an attitude problem, one that causes risk. Even if other people make mistakes that is not an excuse to make the situation much worse, which in my opinion is what you did here. The driver will most likely remember you not as someone aggrieved over their positioning, but someone out for trouble full stop.
The dash cam driver is too aggressive. Read the road..you're approaching a roundabout so there's a good chance you need to slow down and be especially aware of cars 'getting into lane' earlier, rather than later. Why do you keep your hand on the horn so long..what do you think you're going to achieve with it? Slow down and breathe deeply.
This car and man is a danger to society. I saw it on fire speeding down the motorway with a bouncy castle in the back with 5 toddlers and a cow carcus. I don’t want this man is thinking but I’m worried for the health and well-being of him.
