I throw them one of these looks.

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

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.

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.

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…

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

Orrr little light vandalism if you're going to commit
