Unbelievable ! Thats good advice even without the gangs in waiting. Nothing good will come from a confrontation.
I have a few driving stories that were very scary that have changed my driving habits forever. You never know what evil lurks in the next car.
Especially, dont honk your horn at another car. Here in San Diego I recently saw a story where an older man honked at a car waiting to turn at an intersection. The guy in the front gets out with a bat and starts smashing the other guys car's windows threatening to kill the man. Fortunately the older guy had a gun and shot the idiot dead when he was reaching in for him. I think the older guy is still in some legal trouble. But it all stemmed from honking his horn.
I never honk my horn at anyone.
