Ever been riding in a car and tilted back the front seat for a snooze?  I certainly have.  Turns out this is quite dangerous, but for some reason the government and automakers are hesitant to make this fact abundantly clear.   The danger isn't much of a surprise if you think about it...but that's the point.  We often do things like this without thinking about...assuming that "if you can recline the seat, it must be safe to do so."
