I don’t know which country this is from. The CCTV video shows a van taking a left turn, when it gets hit by another, rather fast moving car. That sends the van into a spin which slams two pedestrians.
One of the pedestrians apparently got his by the side of the van so hard, his blood instantly stained the van’s backseat door.
Props to Best Gore member @shehuinihaoge0122 for the video:
