That's a shocking incident of vandalism! As someone said, this could've even caused fire if the burning cracker found its way on to the seat/carpet inside the car. Shocking and sad.

I must tell you that I washed my car this diwali morning and covered it noon onwards just because I was afraid that a firecracker might find its way towards the car and damage the paint. But I never thought that people would deliberately do something as bad as this. Sorry about this Sid.

Looks like case of destructive minds of pranksters at play. Same ones who tie crackers and tin can at end of dog tails.
Poor parenting to be blamed here.

I think this looks like the work of vandals rather than the bomb doing the destruction. I also agree with Navan that the smog in Chennai was so much that it was difficult to drive as one could not see beyond the end of one's bonnet and switching on the fog lamps saw the light getting reflected back nothing else, it was that thick. Here's a pic of the smog taken just from the gate of my residence in Chennai.

Work of hooligans. As you mentioned , it looks more like an intentional act rather than just a prank. Sad.
