Plastic rivet, used to hold other plastic pieces to the underside of the car. Probably in this case it's holding on a plastic splash/aero shield, which is what bent. No big deal.

Damn things fall off all the time. Go look under yours, I bet you're missing a few. And you haven't crushed any alternators in the process.

I was actually pretty disappointed to see that--because I hate those things. I guess it was too much to believe that Tesla wouldn't have any of those damned plastic clips. I guess once I get my (rather unlikely) Model S I'll still have a reason to go to AutoZone.
