What is this?
This is shear tearing in roadside guardrail. Caused by a high-speed impact. For more detail, please go to my flickr set where you can learn all about guardrail impalement*
*No persons were impaled here. The term refers to when a guardrail bends and impales the vehicle

Bad day gone worse for the driver? He/she already had a flat (as noted by the spare on the rear driver’s-side wheel) at some point earlier.
That’s not a spare. It’s a normal tire after the plastic hubcap popped off. It was lying next to the car, although I don’t see it in any of my images.
O.k., on closer inspection, I see that they are hubcaps and not alloy rims. Guess it’s just been forever since I drove a car that ha hubcaps.
