This is an active safety device. What happens if it does not go off when it should? Or as you say deflates too soon (imagine minor initial hit triggers it, second bigger hit comes after deflation)...
Helmets are passive devices. Though they are "single use", there is still likely something there to provide some degree of protection in a second impact (I don't mean a different crash a year later, I mean eg "car then pavement" impacts in a single "use"). A non-airbag c900 is pretty much as safe as the ones with a drivers side airbag... especially now that the airbags are 20 years old and who knows what will happen! Everything is padded in those cars. Passive safety that can withstand multiple hits...
What would be cool is if the airbags reduced the impact causing concussions. Bike helmets (and basically all helmets, in spite of the claims of many) don't really do that... they primarily prevent skull fractures... skull fractures are really bad news though, so I wear a helmet!
what amazes me is the incredibly low helmet use in some countries! the most dangerous thing you can do on a bike is ride it with cars... and it is the commuters who aren't wearing the helmets. It seems that in the low-helmet use countries, the infrastructure is very good at separating cars and bikes... but then people here decide to copy them with our massively inadequate cycling infrastructure... Insane! It seems to be trendy now to bike around in the dark with no helmet, no lights, in dark plain clothes, texting, all while listening to music through headphones... it is darwin vs hipster I suppose...
To me, this is an invention, mainly to somehow appeal to those types... I guess if you don't want to mess up your hair and don't mind wearing a neck brace (it's not trendy to look over your shoulder anyway - the cars are supposed to look out for you after all)... but honestly, if you're commuting far at all, you need to go fast, and that leads to sweat, hence workplace showers... so it's all moot anyway...
sigh...
