First of all: DO NOT LINK, AND DO NOT SEARCH FOR IT
It was a dashcam video, that didnt really show any gore, you could just see something (a brick?) flying through the windshield and hitting the person (the drivers wife?) in the passenger seat. I had seen gore videos before, but this one traumatised me forever. The gut wrenching drivers scream fucked me up and made me feel physically sick, I immediately knew it was 100% real. You could be the greatest actor of all time, but you’d never be able to copy that and I never watched these types of videos again.
Me, having seen beheadings and similar shit, (back then, I was young and dumb) and probably you after watching it: “Why the fuck did I watch that?”
Edit: I also remember this video being talked about on reddit. People were told not to watch it and everyone who did regretted it.
I figure it can’t be worse than the kids with machetes
