The GP got attacked by a flying saucer

[Sudden]

I was going home for lunch and around a turn comes an old oldsmobile at maximum speed. I pull over on the shoulder because he's drifting across the center line. Just as I think I'm safe his hub cap flys off and rolls into the side of my GP. I guess I was too stunded to go after him. It put a small scratch on the side of my car just behind the driver's door. I have his hubcap.
