Car occupants through windscreen - possible?

Some people put the shoulder part behind their backs. Just a lap belt won’t always keep you from leaving the vehicle at high velocity.

Oh, so the shoulder strap wasn’t across her body at all. Gotcha. The variation I’ve seen still went across her body and under her armpit, so still quite stupid, but possible slightly more secure than what you describe.

Good point.

In other words, you don’t literally go through the window, but the force of impact causes the windshield to detach from the car in one piece.

Hey! Is that a Mustang?
