This exact same thing happened to me in Hertz Las Vegas (except it was just under a $900 bill... I also had insurance though a credit card)

Whatever rock it was, it was large enough to make a loud noise. But I still was surprised at how much of a crack it made. My personal vehicle (BMW) which I've driven over 200x as much has never taken that level of windshield damage on similar roads with occasional rocks.

I looked carefully at the Tesla windshield afterwards and had the OEM mark on it, so it didn't appear to be a case where Hertz had already replaced the windshield with a cheaper aftermarket one (like I'd initially suspected).
