breaker bars, long handled screwdrivers and long handled wheel wrenches are excellent, keep one beside your drivers seat! i got abused at some traffic lights by some tool ages ago for some spirited driving, he yelled that "people like me become victims of road rage" the look on his face when i jumped out with said wrench, calmly walked upto his window (which he couldn't get up fast enough) he wouldn't even look at me, these people are all very big until you stand up to them, works for me every time
