That is dangerous as hell. I am certain that was an honest oversight, but what the ..., that could have killed someone! Glad it stayed in place!
About two months ago I was driving in traffic on the main highway through Lancaster when a hammer bounced out of the back of a contractor's truck. It bounced twice on the road and popped up to be dead center and eye level with my head. I thank the good lord it dropped in time and hit the very top of my truck's bumper below my grill instead of coming through my windshield. If I were one split second faster, I would not be here.
Gives me shivers just thinking about it.
