USA : Give the thumbs down to cybertrucks you see driving around.

I have been using this simple, tasteful gesture of admonishment against shitty drivers for years. The affect is powerful, more so than the middle finger, or even aggressive yelling. Today I gave the thumbs down to a Cybertruck at a stop sign. The driver couldn't help but roll down his window, get emotional, and yell insults.

• The thumbs down is a gesture of disapproval and rejection - not anger.

• The thumbs down is not obscene and can be used anywhere in front of anyone. The more polite nature of the gesture lends it more weight.

• People are more accustomed to being met with anger (middle finger, shouting), than measured, level headed disapproval and they don't know how to handle it.

• If someone yells at you for giving them this gesture or attempts to escalate they come off as aggressive and unhinged.
