could this video be real?

i mean since when do airbags deploy so easily?

[Teh Prof]

LOL, no, I've seen it before and read that it was a setup. Pretty funny, though.

repost?

That is staged, but something like that could happen.

A airbag will go off if the car hits a still object at more than 15mph (I think) ... I mean if you got something solid in the bag and hit the sensor there is definitely a possibility.

It depends on the delay of the impact. So for example it deploys from a 10G delay and up. (I actually don't know the right value)

[superdeadman]

well let see
say you stop in like .1 of a second
a=v/t
say you going 15mph = 25kmh= 7 m/s or so
so a = 7/.1 = 70gs

so yeah.. approximately 70gs to deploy airbag unless the stopping time is like close to a second, then it'll be closer to 10 gs
i pretty much see no way that a grandma can apply 70gs with her purse
so yeha - video = BS

I'm pretty sure it takes more than 15mph to deploy airbags. I think this because I totalled my E39 528i by plowing it into a Ford E250 van at 25-30 mph and my airbags didn't deploy.

Of course, none of the other stuff that's supposed to happen in an E39 after an accident happened either...doors didn't unlock, blinkers didn't automatically turn on, etc.

^In what time you went from 25mph - 0mph? It all depends on that.

It takes an impact from more than one of the many airbag sensors to deploy. Most cars actually are able to deploy at 8-14 mph. We had to deal with airbag stuff in the car audio world (reports and such telling where NOT to probe), and now in the limousine business I work for. Heres some more interesting reading:
http://en.wikipedia.org/wiki/Airbag#...ing_conditions

Safer airbags: Manufacturers have now went to higher deployment thresholds. Most airbags are set to deploy in crashes between 6 and 12 miles per hour. This is far too low. Numerous studies have shown that an airbag is not needed unless a crash is at least 18 mph. BMW, Mercedes, and Volvo have long had systems that deploy an airbag at 18 mph if the occupant is seat belted.

Fake video, btw. Airbags will deflate in less than one second as well. Funny, but fake...

Well, I T-boned him, so pretty darn quick.
