Most morning commutes are supposed to be the usual grind. Traffic lights, slow turns, and somebody three cars ahead reminding you that zipper merging is still a mystery to half the country. On Friday morning in Beaumont, Texas, one driver got something much worse. Police say a semi truck lost two 10-ton weights, and both of them slammed into the rear of an SUV waiting at an intersection, turning an ordinary stop into something that looks more like an industrial accident than a traffic incident.
