I do some ''drag races'' as well , mainly with the busses, or a car I can see that is even slower than a jazz-not many cars like that exist tho...
If its moving slower then you are faster
I've found that if I do come across anyone who wants to do that they always slow down so much for turns and roundabouts
Had an experience with some Audi guy
He thought I wanted to take him on because I over took him and didn't slow down for the roundabout
My reason was efficiency
His was just being an Audi guy
A couple of years back, I was heading South on the M1 and came off at Jn 21(?) to go down the M69 towards Coventry. The roundabout is traffic controlled and there was an Audi TT parked at the front of the queue in the middle lane but the outside lane was clear. I was decelerating from motorway speeds and didn't want to stop for the lights so I stayed in the outside lane behind a Mazda and by the time we reached the lights we were still doing 30mph and they changed, so basically, I got the jump on the TT and then on the roundabout, whilst indicating and knowing the way was clear, I moved over into the middle lane.
What I hadn't counted on was his indignation at being jumped at the lights by a Jazz, so he had roared away from the lights and was closing the gap I was moving into. Needless to say, I continued my manoeuvre and then we all had to stop again on the roundabout just before the exit to the M69. So Mr. TT swings around alongside me, in the wrong lane for him, just so he can remonstrate at me from his car. I flashed him the V sign and told him to f-off, at which point he pulled his car slightly across the front of mine and got out - just as the lights changed!
So I just drove round him and his car, laughing visibly at him as he stood there looking sheepish, and headed off down the M69. 30 seconds later, he comes alongside me and starts making ramming movements towards my car! Several times. My reasoning was that he did not actually want to damage his precious TT so I just ignored him and carried on in the inside lane at 70, and after a few more angry arm waves and ramming movements he drove off, at high speed.
I am not saying all Audi drivers at the same, but I think all male TT drivers might be. In my head, the only thing I did wrong was wind him up when he pulled up alongside me. I should have just smiled at him and doffed my cloth cap!
