Windscreen Stress Fracture

[jthtyu]

Drove my Tesla for the first time this past weekend after registration in Jan 2015. Unfortunately, the windscreen cracked after only 30km driving. Fortunately, Tesla HK has agreed to change the windscreen for me today under their warranty. I believe that it was a stress fracture as there was no obvious sign that it was due to a rock chip.

I have something like that I think, but it is not a crack, just 2 small lines which cannot be cleaned on the windshield. Don't know what they are.
