There is nothing funnier than having a convertible riding your ass, and giving them the windshield wiper douche. I had this lady in a tan Sebring right on me (like 10 feet at 50 mph) one day on the Mud Bay/101 turn off. I was a normal distance from the car in front of me. We were headed up the hill and I let fly with the windshield fluid. I could see the blue stuff all over her white visor in my rearview.

God it was so funny. She sped past me but didn't honk or anything, and of course got off at Steamboat Island.
