Thanks for all the replies and comments. I'm going in tomorrow morning to see how much it would cost to repair the damage. In the meantime, here are the pictures...

It's hard to imagine air pressure alone causing this.
I would think that the amount of air pressure necessary would also cause ears to pop, like in an airplane cabin during ascending/ descending -- although the windows don't bulge or pop out here.
Similarly, when I scuba dive to 10m /33 ft, I'm under roughly 2 atmosphere's of pressure -- about 30 psi (at sea level, I'm under 1 atmosphere, about 15 psi). If I didn't purge my mask, the pressure would push it into my face a little but it could never shatter the glass.
There would have to be enormous pressure to shatter glass.
It could also be:
(1) glass too tight
(2) dynamic torsion in the roof
(3) material defect
Any of these could be aggravated by pressure and/ or temperature changes.
If it *is* due to pressure, then it would have to be from some very large pressure gradient above the roof, maybe during high speed, perhaps combined with a sealed cabin and a high fan, plus maybe some steep temperature gradient, like full AC with a hot sun outside. Add some low-frequency long-wavelengths from a subwoofer... and who knows? Your guess is as good as mine..
Good luck with your claim.

Yea, given the mild weather condition of so cal, I don't see how it could be due to pressure.......

It could also be caused by the way the glass was actually attached and torqued into the frame. If one side or the other was torqued tigher than the other, it would be putting un-even pressure on the glass and after enough movement and flex, it would shatter, like it did on my prior car- 04 Toyota Solara. Mine blew up though when I had the sun shade open, so I got covered in glass.

A second on the BMW coupe problems. You also need to consider that it's possibly a manufacturing problem and covered under warranty. Call Infiniti before filing an insurance claim.

WOW, Glad no one got cut! I sometimes leave the shade open to get more sunlight in! I will think twice before doing that the next time.
Just curious, did you hit a bump or a pothole when that happened? Could have been the frame flexing!
