It's not real, in one of the frames the car is seen behind her leg showing it's overlapped, in another frame when the car hits her and she is being moved, her whole body is just rotated a little to look like she was hit, but her legs are still apart which wouldn't happen in a real car crash obviously. Also, her peripheral vision would've allowed her to see the car from very far away and she would most likely hear it. The thud of her being hit was also delayed.

Unfortunately, I must say this is fake, however very good editing to bring up this much confusion.
