So this just happened in GTA V.
Full story. I was coming out of the garment factory minding my own business, when the white car on the right and a cop car chasing it come up the road. The cops shoot the driver and the passenger, who both fall out of the car. One of the cops drives off, leaving the other to watch the scene, but he loses interest pretty quickly and leaves, too.
Other cars start getting annoyed by the white car blocking the street, so they drive into it, some of them thus damaging their own cars (the two SUVs in the middle of the street) and abandoning them. Soon, an ambulance drives up. Two paramedics get out and declare the two people dead. By this time, other cars have decided the new traffic lane is directly over the dead bodies, so they just drive over them. Then, the guy in red picks a fight with the paramedics, FOR NO APPARENT REASON. They punch him out and leave. Then this blue car comes up, stops in the middle of the accident scene, and the people just get out and run away.
Keep in mind that I had ABSOLUTELY NOTHING TO DO WITH ANY OF THIS. I was just a bystander taking pictures.
