They do not "chip" easier than older windshields, but there may be more debris on the roadways of our crumbling infrastructure.
I'll have to disagree- something is different as my 96 Ford with 215,000+ miles has no chips. My 95 Ranger with 300,000+ miles has no chips.
My 18 Transit with 34,000 has 3. My 11 FJ with 110,000 has 3.
All are driven on the same roads.
SOMETHING is different between those windshields.
At least my 19 4R has none but it only has 500 miles.
