I'll play devils advocate here. We have no audio and no testimony from the victim or witnesses in the article. He only exits the van when she walks away.

He could have been unjustifiably distracted, hit the girl, was collecting himself to get out of the van, and then she just walked away. So he gets out and says, "what the hell, you can't just walk away from something like that. We need to call an ambulance or get you to a hospital or something" and her, being a teenager who would rather not engage at all would brush it off with "no, I'm fine, fuck off".

What do you do? You can't detain the girl. So she leaves and what? You call the cops and say "I fucked up and hit someone with my van." Who does that help? Now shes lost in the crowd. You can't just stay there, so you drive away. What else is there to do?

He's 100% guilty of hitting a pedestrian who was plainly walking in a clearly marked crosswalk where it is likely busy with other highschool students as there are clearly others in the video. Don't get me wrong, fuck that guy. We can fairly judge him on that account. And that verbal interaction absolutely could have been him victim blaming, but that is conjecture. I'd believe any first hand witness over him, and pretty much any secondhand retelling from someone a witness spoke to. But we have no evidence whatsoever about what was said.

That's a ragebait title.
