You know that feeling you get when you're driving on the freeway behind a truck laden with metal pipes and your immediate instinct is to get away from that truck before one of those pipes flies out and impales you? Well, it turns out that's not such an irrational instinct.

Police in Livermore, California, are today attempting to get to the bottom of an accident in which a 33-year-old man was killed when a pipe crashed through his Volvo station wagon's windshield, impaling him. According to the local CBS affiliate, officers are still trying to figure out where the pipe came from.
