I had to replace my windshield recently as well.
Tesla windshields do seem to be more fragile than on most cars I've owned (an Isuzu; several Dodges, pickups and sedans; a Pontiac POS; and others). On rare occasions I heard the sharp crack of a rock hitting the windshields on nearly all of them, but few resulted in a star in the glass, except for the Tesla. EVERY time I hear a rock strike the windshield, I find some glass damage. Fortunately, SC requires the insurance companies to cover the cost of glass repair totally, including the deductible. $1600+ Tesla windshield replaced at no cost to me. [that's the ONLY positive thing I've ever found in this 3rd world state, btw...]
