i was going down the M6 a few years ago, near brum, southbound on the M6 where the M6 toll joins and there are 4 lanes, and there were some roadworks, with a 50MPH speed limit and those average speed cameras closing down the outside (4th) lane
in those sorts of scenarios, you usually end up in the first or second lane, because your all travelling at pretty much the same pace, but on this occasion, there was enough traffic to push me out onto the 3rd lane.
pootling along, creeping past someone going 52mph on the cruise control and the car behind me pulls into the second lane, and a car comes up past him, behind me, doing 60+mph.
he comes close enough that i can't slow down and pull in behind the car i was overtaking, thus letting the fool pass me, so i have to make my way past him, however there are a few cars in front of him as well, so i have to pass maybe three cars, taking no more then 30 seconds.
well these 30 seconds were pretty precious to him because i can see his lights flashing, beeping and gesticulating wildly.
nothing i can do, the people in the 2nd lane are oblivious, and i amnot willing to go faster, so 30 seconds later, i pull in, he goes past me like a bullet, horn permanently on, comes in front of me and slams his brakes on....in the second lane of the motorway
now i was doing around 50mph, so i have no choice but to slam my brakes on and swerve into the cones separating the 4th lane, knocking two over as i came to a stop.
luckily there was no one behind him in the 3rd lane or i would have been toast.
anyway, after a minute calming down, a motorway engineers car comes along, flashing lights and says he saw what happened on a camera and came to see if i was ok. apparently he was watching the monitors for accidents or breakdowns, and had informed the police, who stopped the bloke further down.
needless to say i dont beep or get in anyones way unless i have an escape route, its not worth the hassle, and certainly not worth mine or my wife or daughters lives...!
