Many years ago if I was stationary I started turning around and blowing them a kiss rather than the finger. That seems to step up the red mist several notches and is often amusing (for me anyway). That might or might not have had something to do with me being arrested in Oman for giving the finger to a Nissan sunny full of locals, though that's another story entirely and I was driving an Outlander, so not appropriate for this forum.
