I think the diesel method is the #1 best, and least provoking approach to employ when dealing with these questionable individuals.

I have never encountered a problem feathering the accelerator on a car with no ALDA and an overfueled IP. It drowns them, they think there is something suddenly wrong with your car...They back WAAAAAAAYYY off. It works EVERY time. And again, they do NOT get angry. It wakes them up. Every other method is just begging for confrontation.
