Man that first one is screwed up! i really don't think he survived. Well, it doesn't look like it. I mean his head ended up out the back window and it looked like the car landed on that side. whoooah. Glad it was him and not me. I bet he woke up real quick that time.
Definitely a bad accident but i think he survived. At the very end you see him grab the headrest so doubt he was dead. Plus the car was almost stopped by the time his head went out the window. But that's a bad deal either way.
