I think you are okay if nothing else happened.
I got hit in the face with a McDonald's Cheeseburger thanks to Road Rage, not kidding.
We were at the Holland Tunnel going into NYC, summer time windows down, my friend who was driving pulled a dick move and did not let the car behind us in breaking the common courtesy flow of every other car. Dude was cursing at us and beeping the entire time through the tunnel and when we got out of the tunnel and the traffic broke up a little he sped up on the passenger side, my side, and hit me square in the face with a wrapped McDonald's cheeseburger.
Dumbfounded, I looked at him, unwrapped it, and proceeded to eat the entire thing. This made him furious beyond belief, so he followed us for a good 5 blocks, until my boy who was in the back seat said pull over, which the driver did, and my boy got out of the car, as did the driver of the other car, and my friend laid him out with one punch like it was the fucking movies.
It was all crazy as it sounds and ever since I do my absolute best to avoid any additional road rage incidents.
You'll be fine OP. If they didn't do anything as it all went down its over.
