You not confusing threads Davo - cannot see a post from an axemurderer in this thread - although it has been a long day.
You and others are correct though - the safety restraint systems are 'staged' and will only trigger if necessary - according to the manufacturer settings. The smart little black boxes record G-forces, change in acceleration / deceleration and if a threshold is passed, they will deploy the necessary safety device.
YEP - airbags do cause serious injuries - an explosive device triggers the bag with a very fast deployment speed and they will break facial features - they may also save you, so the increased protection - whilst at a cost - is worthwhile.
My prang - yep, here's where I'll bang on about it again, was a strong, full brake force deceleration from about 80kph and I reckon I hit the other car (which turned in front of me) at around 30-40kph, judging by the crush to the front of my car and on his. Seatbelt pre-tensioners deployed and locked me into the seat - airbags did not deploy, as there was no need..
