Grr. I was next to a truck at a red light once with his bass rocking the asphalt, windows down, so I thought, okay, two can play. So I cranked up my Beethoven as loud as it could go and rolled down my windows on his side and started rocking my head to the music. I saw him glance my way in alarm just before he rolled his windows up, lol, and then the light changed. Very satisfying.
