I suppose you'd had to be there to understand my actions in full, But I never put anyone in danger from my driving, He/She din't have to exactly carry on overtaking in the way the mini did.. Possibly a bit of road rage build up release also (the mini)..
Sorry bud, the minute you said you decided to "put some pressure on the muppet", you more than doubled the danger level to everybody (road users & peds) that were around you.
Don't get me wrong, I'm not the worlds best driver by any stretch of the imagination.....and I have had the "red mist" more than once myself out there.......but I have no sympathy in this case as you (by your own words) exhibited an even worse case of bad driving than the original idiot you encountered in the Mini.
I have no doubt you made the Mini driver think twice the next time, and I have even less doubt that you felt one hell of a lot better at the end of it, but lowering yourself to the same standards as others doesn't work at all well in the long run.
