FNC had some video of the crash this morning. Right after the crash you can see a clear liquid, sloshing over the inside of the roof and streaming down the interior of the car. I'm assuming it's gasoline. Scary. Did the gas tank rupture?
I originally thought this too, but looking at the video again the fuel spillage you see is from a camera mounted under the car looking out the back. I could be wrong, but check that if you see the video again.
