People. Those are OEM with a seriously not concerned owner. These bolts use bolt caps to prevent that from happening, just like Audis, VW, Lambo and I think Bugatti.

You need to make sure to take them off and put them back in whenever you do any type of service that require taking off the wheels.

Maybe the dude just had bad luck, didn’t remember to put the caps back on or went to a place where they did not do that for him.

In all cases: Shame.
