When Leonie and Arjen roll out of the car, Leonie has lost her hat and her arms stretched, crushing the hat with her hands. But in the next shot, her hands lie sideways and the hat is untouched.
In the front shot where Leonie is being pulled in, Arjen his cap falls off behind her. When the shot changes to him, the cap is back on his head and falls off again.
Leonie her hat falls off twice during the struggling, but in the shot of Arjen helping her, the hat is nowhere to be seen.
The effect of the car moving is done by sliding the whole frame from left to right. You can clearly see the background moving along with it.
You can see the bright LED-light standing behind the car when Leonie is lifting Arjen.
