So far this weekend, I've seen several vehicles whose wheels have been in a somewhat naturally untennable position. Here's one that I didn't witness, but makes for shocking viewing!
Watch as the bus is hit. From inside the bus involved. Watch how they all stand mortified at the impending crash, and how they're each affected by it. Like rag-dolls in a washing machine. Makes you wonder how there were no serious injuries, and think about what happens in a crash. Especially when there are unrestrained passengers...
Now THAT's what I call Mechanism of Injury.
Remember - wear your anti rag-doll device. Popularly known as seatbelts.
