Originally posted by tim60 I read a paper 20 years ago that said "the greatest discover of modern philosophy is that no-one ever saw a stone break a window." Cause is, fundamentally, unobservable.

I'm with sherrvonne.
I live in the mountains. There are several rock quarries nearby. Everyday as I travel into town, headed for the World's Largest Building, my route is shared with all the dump trucks carrying crushed and broken rock.
My cars and pickup all have broken windshields. I've seen every stone that has been tossed my way as it has busted perfectly good glass.
It was such a problem that I have done two things.
First, I bought a rock chip repair kit. A worthwhile investment, as it prolongs the inevitable windshield replacement.
Second, once cracks begin to form, I simply draw a line with a Sharpie on the inside following them to reduce glare from the sun and headlights of oncoming vehicles. And then I wait until the state patrol stops me and issues a fix it warning before spending a few hundred bucks on new glass.
