It does not appear that the man was killed in this video as he slammed into the car while upright, with the back of his head making contact, so he didn't take the brunt of the car's kinetic weight as it moved forward, and it wasn't like his head was caught under the wheel. I don't see any details in the social media post's chat thread giving us more information.
But I will issue a reminder that videos showing someone being seriously/permanently injured or killed are prohibited in the SC. Please review the rules.
If I see a video posted of someone being killed in this forum, I will issue dubs, and potentially a ban.
