Why did the guy in the car come out? Wouldn't it be safer to stay in the car as protection against things falling on your head?
But wouldn't the roof of the car provide some protection from smaller debris falling on you without you needing to "dodge", and anything bigger (like a building) you are unlikely to be able to dodge anyway.
It seems intuitively safer to stay inside the car (it's built in some ways to keep you safe), and it won't necessarily be hurt by the movement itself.
