Only if you do it outside the vehicle. This actually came up years ago when I took a motorcycle course. Since you’re always outside the vehicle I guess you can’t flick people off.

I throw them one of these looks.

Orrr little light vandalism if you’re going to commit

It can also get you shot, people are insane in their cars.

Bro, as a Massachusettsan born and raised if you dare touch my primary form of expression ya gonna get a hot cuppa dunkins in the face. That’d be like banning wicked sick donuts in a rotary.

I point and laugh at the ones I see here in Seattle. You can do a pretty good show of it from a bike while passing them being stuck in traffic lol

Also a chance you’ll catch one of those guys carrying in their cars - that’s their thing. No need to put yourself in the crosshairs for an unhinged person…

This feels like such a thin reason to get a ticket if you ask me. A rude gesture is just a rude gesture. But… be careful out there! I feel safe enough to flip them off, but I encourage safer forms of heckling them, like pointing and laughing.
