Track cars = windshield crack?

i'd like to bring this back up for debate with this video.

The beginning shows clearly no crack, and i edited out the middle of the lap just for time and file size, i'm nowhere near any other cars.

Since I posted this thread my crack is now 20 inches long and there is a 2nd crack that is also 20 inches long.. both in the same direction and coming from the same place. Track crack = true
not sure if its similar chassis setups... but 20+ track events per year will do it.

However, i ran ok on sat, and it happened on sunday, when i really wasn't running as hard.
But tonight i'll see when i pull the wheels, swap brakes, etc.
This is the first time i've run without an undertray, and i noticed my coolant temps were up about 10 degrees, but it's also the dead middle of summer. But the oil temp was down.
I didn't get any video from the link, only audio. Anyway, you should be able to tell a rock vs stress crack. A stress crack starts from the edge and not from a rock chip or bullseye which will not be on the edge. If it starts from under the WS wiper valence, then it obviously wasn't a rock that caused it. Stress cracks in a windshield are real esp in unibody cars with the urethane adheisive they use today.
One thing that determines how easy a WS it will stress crack, besides the body stiffness, is how the WS was made at the WS factory. This does not have anything to do with the 'raw' glass, the sheet itself, but after it is cut/bent to make the WS. If made "right", there will be a compressive stress around the outside of the glass which makes it stronger than if it's not there; it is almost like a minor tempering effect. I worked in an auto glass factory and dealt with issues like these and researching the whys and the variables.

Crack comes down from the top, right above the rear view mirror, and now comes down 1/3 of the windshield. My true thought is that maybe the KW's i have, were set too soft for homestead, and i was possibly bottoming out on the drivers front corner, and after so many times, it just gave way.
I honestly didn't feel like i was ever bottoming, but i can't 100% say for sure i didn't.
Was at Pocono South three weeks ago and I developed a crack that started from the top corner of the passenger side. End of the day it was almost 13-14 inches long. I don't recall any stones getting kicked up that day as it was a wet event, and there's no sign of a rock chip at all. I suspect it's a "track crack" due to the banking left on the oval on which we were averaging 100-110mph.
They aren't concerned about it breaking?

I'm starting to believe my own track-crack theory even more now...
