In an attempt to be more diplomatic I’ve decided to change the single digit hand gesture I often display in response to motorist stupidity. So now if you honk at me, try to run me over, spout nonsense like “get off the road!” I will respond with a big thumbs up and a smile.
Just be aware that it probably doesn’t mean what you think it means. It’s just less likely to incite negative emotional responses and possible violence. But it is deeply sarcastic.
