Recently i have used the mod: Gavril Vertex Made by inn0centjok3r which has an airbag light indicate when a substantial frontal crash occurs which showes that the frontal airbags have been fired. this is a cool touch that i think should be added to all cars in beamng that have "airbag" labled on the steering wheel or passenger side dash as it will add to the realism of the crash and beamng as a whole.
Why have air *bags*, just have a hair dryer on max blow your head back in place in an crash. Air -bags.
