i would like to see a slowmo crash test of both the front and rear air bags hitting the drivers/passengers heads at the same time...

but how knows might work.
if your thinking about explosive airbags and not static air bags that is... i would more look into the uprights sticking up from the seatbelt towers and also a bag seperating the two passengers...
the amount of weight gained from all this would be pretty ugly.. but if your talking a road car and safety then sure why not..
only thing is the air bags need to be fully deployed before the victims melon lands on it other wise your copping too much of a blow
