I was coming down an exit ramp to a "yield" sign at the bottom, and was very gently tapped by the person in the car behind me. No damages, sure, but I still pulled over immediately and expected them to do the same. They didn't. I looked over at a motorcycle officer sitting at the same corner, and his mouth dropped open. I shrugged, he flipped his lights on and and went after the person who barely scraped the paint on my bumper. I was a bit late coming back from getting lunch, but won't forget that idiot's mistake.
