Drywall and metal studs aren't much of a match for anything. On more than one occasion we put body parts (or whole person) through the walls at the Karate school. We used to have a plaster and paint party before every big testing if there would be visiting judges.
As to no charges filed: What the heck? It's legal there to drive into a building and maim people? Sounds like a fun way to deal with people you don't like...just run 'em over!
