I am that driver

On a recent trip to Costco I was driving. I was behind an old car that was moving at a turtle's pace. So slow it missed going through two green lights. After we sat through one full cycle on the second green light cycle I honked. I honked some more and he started going 5mph and then slowed for the yellow light. The traffic behind me was honking. People beside us were honking. Everyone was honking. Then I noticed it: my beefy horn had turned to a meep-meep. I wore my horn out. The car does not even have 50k on it. I guess sometime you just have to let people know and that is how I do.
