Air bags deployment
I was driving in the rain when my car
started hydroplane at 70 mph when a
did 3 360 spins before the ass end of
the car hit the guardrail and my
airbags never deployed
Consider yourself lucky you didn't hurt yourself or others. Airbag deployment needs certain cases in deploying, like acceleration and location of impact. Most sensor are located in the front bumper for frontal collisions to keep you from going through the windshield and are not meant to deploy with just a rear collision. If you are asking if the airbag system was at fault, I'm pretty sure that isn't the case.
My 213 was tboned without air bag deployment!
