They moved the wrecked car on a flat bed truck from T3 back to McLaren after the completion of the race. Because the track is full of people by this time the truck was moving at a very slow pace. I happened to be walking along the track and had a chance to take a good look at it up close. It was completely destroyed, but the core cell was completely intact! Incredible strength. Here's a pic of it. I was so preoccupied with checking out the wrecked that I forgot to take a photo until it was past me.
