"I'm the guy in the yellow car. This guy was trying to cut my lane and I honk back. He called me out and within two seconds the swing happened. I'm was with my two little ones. No point retaliating and showing my kids to do the wrong thing. Anyways police are on the case. Please watch out for this car plate."
