Jesus that's bad
Surely no seat belts???
I thought your chances of surviving a high speed crash increased if you rolled like this rather than hit something
They were thrown like rag dolls. Unless the seat belts failed hard to imagine, the glass smashed and their arms went out the window pinned under the car and presumably ripped off under the weight as it rolled.
An old boss of mine crashed a hire car on the m6 toll we me in it. Bloody tires bald, been raining back end went, spun several times heading for central reservation at 70mph. I just pulled my arms tight in over my head convinced it was going to smash and flip. Luckily bounced us back out few more spins but never rolled.
