^^ Im not completely sure about what needs to happen for them to deploy.
I had a slight mishap in my older VTEC Prelude. I spun out on a tightish bend, and hit the passengers side into a clay/rock bank. It wasnt an overall intense impact, but i watched the airbag deploy. It just looked like a limp dick. No inflation i saw so to speak.
This was the aftermath (no idea who the person in the photo was).
I guess it was just a perfect situation for the airbag to go? It would have been moving at about 60-70km/h when it hit, and i was sliding more along the wall rather than into it if you know what i mean. It wasnt a head on impact.
Maybe its because of a crumble zone? The impact was solid enough for the front cross-member to sheer off the corner of the sump.. clearly But it jst didnt FEEL like it was a hard hit.
The other thing, maybe the technology between a 1992 airbag, and a 98+ Airbag, from the 34 is different to avoid writeoffs with minor damage deployments. Because as far as im aware, if an airbag deploys in NZ, the cars toast regardless.
Oh, and edit: The point is, from the post above about the airbag tests, it would be pretty safe to assume i was not hard on the throttle when i hit the wall, considering it was after stepping out to the right a good 50-60', then spinning left into the wall. And being a n00b young idiot i would have been hard on the anchors.
