3.3 milion deployments and 175 cases where something went wrong...
I think that figure of 175 is just the number of people killed when faulty airbags 'go off' when they shouldn't. The article in question is suggesting that, even when they 'go off' as designed, they still kill more people than they save, it's just that these deaths are attributed to the accident, rather than the airbag.
"The new analysis directly contradicts earlier studies about the effectiveness of airbags, which have been required for drivers and front-seat passengers in all cars since the 1998 model year in the United States."

There may well be some low-speed accidents where the airbag ends up delivering a bigger blow to the driver than the crash itself would have done. And, there may well be some people small and frail enough that the impact of the airbag could be fatal.
I imagine the airbag deployment system is calibrated so it won't go off if it thinks the airbag impact would be worse than the un-airbagged crash, but there must be a bit of uncertainty in determining this, and with 3.3 million deployments, all of the edge cases are going to get tested.

While the article doesn't include the full paper, I get the impression that it goes something like this: The 'original' studies were only based upon fatal accidents, whereas the 'new' study also includes non-fatal accidents, and by comparing 'like for like accidents', there were more fatalities in cars equipped with airbags than in those cars without airbags, all other factors being equal. (not just low speed crashes where the airbags went off when they shouldn't have)
Hope that makes sense.
EDIT: the authors have asked that this be independantly verified while there are still some cars on the road without airbags.

AFAIK, these days in the UK an airbag won't deploy in an impact under 30 mph. When airbags were first introduced the deployment impact speed was lower and there where a lot of additional 'injury claims' due to people gripping the steering wheel and getting friction burns on their arms from the airbag.
An example of the energy contained within the the airbag deployment system.
Anyhow, I don't know if it was a good thing or not, when the Vectra my father was driving bounced off of two trees, the side window burst and the airbag mashed the glass 'diamonds' into his face. He was ok asides from bruising (and a pepperpot looking face).

leave it to the Russians to "test" a system using real people. LOL! (Putin was probly the trigger man, lets be honest.) i hope this poor idiot doesnt live the rest of his life in a wheel chair.

HEehehehehehe !!!! Hilarious !!!
->
There actually aiming for other cars based on criteria for survivability. i like the motorcycle dilemma ... helmet or not?
The random number generator is interesting, but I bet congressmen and corporate officers' (rich people) vehicles will be programmed different. As you and I are filthy savage commoners, therefore expendable.
