    When I was driving home today I heard a bang from rear seat and when I turned back I saw that the rear left window was completely shattered with a big hole in the center. Lot of glass pieces were lying on the rear seat. Luckily no one was sitting in the rear seat.
    Any idea what could have caused this? Has anyone experienced/heard about glass exploding on its own?

    Did you check for any stone inside? If there wasn't anyone around and vehicle was in motion, someone might have thrown a stone at your car! The glass is tough and fitted properly and would not break if a tree-branch hits it, if you went though some tight space on a narrow road. I am sure these logical possibilities you must have considered.

    The glass must have shattered due to a flying stone either from other vehicle or some one threw the stone. Looking at the damage, it seems the object which hit the glass must have been sizeable and cannot be a small pebble from passing vehicles. If the glass were to shatter on its own then it would have started with a crack and then shattered.

    Are the glass supposed to be shatter proof??

    i have seen in my office too, a nice 4mm thickness glass of 10x6 got a break in the similar fashion,like spider web.its very hard to judge if it's due to stone or due to environmental conditions.

    The pattern in which the glass shattered most probably some object hitting it in centre. Look at the pieces at the centre and the crack marks radial inward toward centre.

    When did this happen? Bangalore, what time? Have heard cases of robbery in Bangalore(Outer ring road) where they throw stones at windows.
