Anyone inside that car would have been in bits. Trust me, I've seen many clips that show the aftermath of impacts like that. Limbs are normally on the road or verges and the rest is normally tangled in the wreckage. What's worse is that occasionally some are still alive.
No, I'm not morbid but when my kids where 10 & 12 yrs old I showed them horrific footage of road accidents, I mean as bad as you can get. I then told them "this is what happens in real life when you get in a car with an idiot, or a driver that;s been drinking".
It worked LOL as they are both young adults now and they STILL mention that day LOL
