Funny looks, stares, even yelling out the window... all easily ignored and have ZERO physical effect on anyone. Even flashing lights and honking don't directly affect anyone else. Just ignore the shit.

Road rage to me is intentionally cutting people off, brake checking, swerving/blocking lanes, speeding up to not let people pass, intentionally driving slow, throwing trash out of their windows, etc.

Anything that affects another driver's actions directly.
