If that happens to me, depending on the other's driver temperament, I would either:
a. stay in my vehicle and roll down my window to talk to him (pag medyo ok pa)
b. get down from the car and talk to him. I'd try to pacify him if I can.
If naghahamon sya ng away, I'd tell him wag na lang. Not worth it for both of us. (kung kasalanan ko.. hehehe)
that's why I leave my guns sa bahay. Mahirap na.
I remember one incident in which at that time dala ko baril ko. There was this Pizza Delivery Boy nagmamadali and he crashed sa side ng Strada ko. Even though it was all his fault, he promptly got up, fished out his balisong and went at me.
I took out my gun and said, "ibaba mo yan..." Ayun. This snapped him back from his enraged state. I then told him to drop it on my passenger side.
Afterwards, nagmamakaawa na ibalik ko na lang daw yung balisong nya. Ano ako, tanga? Sabi ko na kasalanan na nga nya, mabuti't hindi ko na naisipang habulin sya para sa damages ng sasakyan ko.
