Front sunroof glass (the portion that moves when the glass is opened) spontaneously shattered. this occurred while driving at ~70mph on a smooth highway in minimal traffic; clear weather, roughly 60 degrees f. i did not pass under any overpasses immediately preceding this event. i normally leave the sun shade back and did not notice any cracks. as i was driving, i heard a very loud noise and immediately glass started falling on me and throughout the cabin. i slowed and exited the interstate, pulled into a safe area and immediately took pictures and called my insurance. the remaining glass appears to be bowed upwards.
