You're average car driver... they panic. On the other hand this guy laughed and left.

Last place I lived had an incident where a driver taking a left turn ran onto the curb and over a rather obese guy. Driver decided to try and flee, but his front tires were off the ground on account of the guy he just ran over

So the driver did what many drivers do: Rocked the car back and forth to get away. Got off the guy after a couple tries and ran off. Coroner's report stated his medical opinion was the victim would have lived if the driver had stopped the car and helped, and that the victim died due to organ damage suffered from the rocking back and forth

The driver was sentenced to ~9 months in jail, out after ~6 months. His license was suspended for a year. People like that should never drive again, but he argued without a license, he couldn't work and if he can't work, he won't be able to pay the civil penalties to the victim's family (spoiler: He won't be able to pay them either way)

People are weird. I'm not excusing behaviour but in some situations of chaos I'm in control and directing so long as it's work. Outside of work in those situations I can have a tendency of flailing my arms not knowing what to do.

IMHO it's bad but people who leave the scene it should be attributed to human nature the larger concern is after they calm down if they turn themselves in. That to me should be more judged upon.

That said, people, if someone is hurt don't leave the scene!

Perhaps very late to your second minimum wage job (that you really need to barely make your family's rent) where they have a habit of letting people go at the drop of a hat while being blasted in social media about how hard it is to find a job right now.
