How do nails/screws get stuck in tires?
One would think that a nail or screw or other piece of metal would be lying flat on its side on the road, so when a vehicle runs over it, how does it raise up to puncture the tire?
Even if it were sitting upright, wouldn't the vibrations of the approaching vehicle cause it to fall over?
