In the Garage
Yes they do, unfortunately I found out the hard way last Sunday.
Air Bags should always deploy when activated regardless of age. Basically they are a material bag carefully folded up with a small explosive charge inside the bag. the explosives are activated by a an electrical detonator. when any of the cars sensors are activated a current is sent down the wires to the detonator which in turn sets off the main high explosive charge inside each bag. due to the speed at which the high explosive burns at, is the force that inflates the bag faster than you would believe.
