It is less agitating to some peoplelately I'm noticing this new phenomenon of flashing the headlights instead of honking. What gives.
There's sections in The City where honking will get you a $350 fine. Let's say a cop notices right by Midtown Tunnel, there's a BMW and a TLC plated car in a honking match... guess who gets the summons faster?!?! There are even visible signage about it, only in certain areas (Crown Heights?! You can't at all!).
