I'd love to see people like that hauled before the courts and be held bang to rights.
Out of interest, how did you escape from that probably quite imminent collision?
I'll quote the post I made at the time, with a little (EDIT - a lot actually!) added to give the full details of the story so I don't look like a totally innocent bystander - I no doubt riled the guy but it wasn't intentional.
What's even more alarming is when you go to overtake someone on an A road and they think it would be really clever to move into the centre of the road and perform an emergency stop in an effort to block you as some absolute lunatic did to me last weekend. I'm still not entirely sure how I kept it out of his back bumper and out of the scenery.
The "incident" began on a short section of dual carriageway between here and the M1, which has a roundabout (2 lanes for straight on) in the middle of it. It's a pretty quiet roundabout with little traffic coming from the right and visibility is good, so if you are on the main route you can carry a decent speed over it if you have a car with half decent grip levels.
The Golf has coilovers so I can carry a lot of speed through roundabouts. An MG ZT estate was in the left lane, moving quickly up the D/C but it slowed down significantly for the roundabout. I didn't - and in the process overtook the ZT on the roundabout itself. Conservation of momentum meant that I passed the ZT very quickly - he slowed down a lot, I didn't have to.
Obviously an MGZT is a fair bit faster than a Mk2 Golf GTI, so about 100 metres up the D/C he catches and passes me like I'm standing still (I'd maintained a speed of around 75mph) By the time I got to my turn off for Loughborough approx 800m further down the road, he was out of sight and out of mind.
The road to Loughborough is a single carriageway NSL road. It's fairly straight, good surface, a couple of junctions to be aware of, and has a set of traffic lights at one point. When I came up to the traffic lights the MGZT was sat on red waiting to pull away.
He pulled away, very slowly and didn't get much over 30mph so I decided to overtake him from a fair distance back (like in those old motorbike safety adverts, remember them?) as soon as he saw me closing on him he accelerated too and outdragged me easily - so I didn't bother taking to the other side of the road and eased off instead. He did the same, and slowed down to around 35 again.
I thought sod this, not playing games all the way to Loughborough so took a good run and indicated and moved out to pass him on a straight stretch.
He accelerated, moved to the middle of the road and then performed a full emergency stop. I braked hard, locked up, swerved, and came to a halt diagonally across the road with my nose pointing towards the left verge and alongside his rear wheel. I opened the door, jumped out (at this point I had absolutely *no* idea how I was going to handle the impending confrontation) and the MGZT took off like a scalded cat.
I took a deep breath and decided the best thing to do was to remove myself from the situation. I wanted to go after him but really, what would I have done, rammed him? Kept trying to overtake him until one of us went off?
There was no winning solution for me so I parked the car on the verge, took another deep breath, called 999 and reported the incident as best I could. When that was done I carried on my journey.
That's the first time I've typed that up properly, I can still remember that feeling down my spine when his brake lights came on and his car squirmed as they do under serious braking, the smell of my tyres as I locked up, the subconscious realisation that braking alone was not going to prevent a collision and then the wave of "WTF!?" that hit me as soon as I came to an actual stop.
tl;dr - I avoided a collision by being alert and having half decent control over an old shed.
