I was alone at a tram stop late at night - not much traffic around - then heard this "whoomp" and saw a car land on its roof and slide for several metres. It had hit the safety zone on the opposite stop, which is a concrete barrier that forms part of a protective zone so that people can safely wait at tram stops in the middle of the road. Unfortunately it's also good for launching and flipping cars!
She was very lucky and just had a nasty concussion. Car was new, and a write off. She must have fallen asleep at the wheel.
(If her car had been a foot or two on the other side then the car would have come directly towards me as it launched...)
