Air bags

[b2428]

Im not sure where to post this but I have a question in regards to airbag speeds. This misses was in an accident involving a hiace campervan and her k12 Micra on Thursday. Both her and the towie seem to think that she hit this thing at roughly 40ish km/h. The force was enough to snap the engine mounts and bend the left rail all the way back. The micra did well didnt deform around the main structure but twisted the right side of the front around to the left a fair bit. All this was done without the bags going off. I find this to be quite a worry considering the estimated speeds as well as the actual damage to the front end of this thing.

Hit the van just in front of the rear left wheel. Barely a mark considering the considerable damage to the front of her car.


Any ideas as to if the bags should have gone off or not?
