I agree the cammer needlessly sped up, however, the other driver emerged onto a 50mph road and didn't bother to accelerate. So what the video showed here was two morons.
Dash-cam driver had plenty of time to slow down - they sped up, almost ending read-ending the car in front. Needless agression. Then makes it worse by driving two close (remember the two-secnd rule? Clearly not), then doing a piss-poor over-take: limited vision on account of being far too close, on the brow of a hill and across two side roads. So flaming what if the car in front is going too fast for you.. you don't take stupid risks like that.
And coming back to the start of this video. It doesn't take a lot of brains to realise, that when you have a bend fairly close to a fast-moving roundabout, you are going to get instances such as this. Dash-cam driver could have simply held back and got on with their day..
Another one. Yes the driver in front pulled out, but just look at the attitude of the dash-cam driver..races ahead to tail-gate as a form of aggression. Just making the situation worse, not better.
My only complaint towards the Aygo driver is they've pulled out onto a 50/60mph round and proceeded to drive at 20mph. No sense of urgency which is somewhat needed when you're joining a 'fast' road
The road design adds risk; you have a junction very close to a bend, and fast-moving roundabout.
The Aygo driver was in the process of pulling out before the dash-cam driver had finished fully exiting the roundabout. They flashed their lights to say sorry and began speeding up. Yes they were going slower possibly to allow this impatient loon to get himself one step closer to hell/heaven quicker than everyone else..
