My car has gone through like 6 windshields, 1 of them was a semi truck tire's tread blew the hole windshield out. They all chip easy and being in the desert there's plenty of rocks here to get flown into the windshield. My car and my aunt's 2013 VW's windshields are pitting, with 20k miles on mine and 12k on hers. Not horrible pitting, but too soft for my taste. Both are windshields from Safelite. One is a Pilkington the other is a weird brand named.
