I have to admit I have done something similar before. I took an off ramp (a loop back and was in effect about a 180 degree turn) with a young stud in a Firebird right on my bumper "pushing me". What he "didn't know" was that I was coming from autocross with my race tires still on the car. I took the inside line at close to three times the "recommended" exit speed. The last I saw of him in the rear-view mirror was him fighting the wheel to stay on the road.
I never saw him again ......
