I noticed that too but can't tell whether it's a plastic "rivet". If you look at the plastic fairings on your car, you'll see that many are held to the body with a snap-fit plastic connector. These are also used as blind fittings on many interior panels (such as door panels). They break and detach often enough that my local hardware store carries the more common ones.
Yep, I can confirm, there are hundreds of those throughout the car to connect pieces that are either cosmetic or not tied to the safety or performance of the car. For instance, the plastic shell inside the frunk is connected to the car with them.
Personally I think the ground clearance is still a bit on the low side.
It looks like it lost a bolt or something in the first impact image... oops.
