So, how loud are those things while you're in the car with one
ex-pand/ploding?

I t-boned a 17 yr old that pulled out in front of me, I was going
about 50.

I did close to the same thing; saw the suv pull out while I was going 60,
but got slowed to perhaps 35 or 40 MPH before impact.

They are fricking LOUD ! ! ! Imagine two or thee 12 ga shotgun shells going
off 2 feet in front of your face, and another couple going off in front of
the passenger's seat.

My ears were ringing like crazy. I got out and checked on the other car,
talked to the first people that stopped and made sure police were on the
way, and the police were there in a few minutes. It was then I walked over
to my car to get something off of the seat, and I noticed the car was still
running. It was the first time in 8 to 10 minutes that my ears were not
ringing so loud that I was prevented from hearing a running engine.

I never felt the bag hit my face or body, because I ride pretty far reclined
and far from the wheel, and always wear seat belts. I saw it coming and
braced on the wheel pretty hard, I guess.
