This is something that many people have neither heard of nor even thought about. When the front airbags are triggered, which can happen because of a mere bump to the vehicle at speeds as low as 12mph, those airbags [explode outwards] at between 165 and 200mph. They are most certainly not nice fluffy cushions, and if you have one or both of your feet up on the dashboard at the time, the results will be serious and can even kill you.
