I have a 2020 Outback with 25k miles and have replaced the windshield 4 times! I'm a very conscientious driver and don't follow close to cars or trucks. What you would consider the smallest rock that would cause a chip destroys the windshield. I had an Acura with 170k miles and never had to replace the windshield. Anyone else experience this? Fortunately, I have full coverage glass coverage but Im sure the insurance company isn't too happy.
