I have. It damn near broke my nose. I sort of believe the "bullet" thing because there was smoke coming from the dash. I jumped out and I was standing out in the rain with blood dripping from my nose into the grass. Wearing a seatbelt saved me a lot more harm than the airbag, though. I had a nice color-changing bruise on my shoulder and chest for about two weeks.
My Gov't Mule buddy and I were coming home from work on the other side of town. (praise Jesus, i don't work at that store anymore) He liked to take a 'backroads' route because it was more direct than driving through the city. So we're coming home and it's raining, we're approaching a slight hill and a car is coming the other way, there's a slight curve and the car starts going sideways. OH SHI! BOOM! It happened that fast. T-boned the car. Luckily my buddy had an older model and sturdy Jeep Cherokee or things could have been a lot worse for us. I could have had broken bones in my hands and my knees had some good bruises on them from hitting the dashboard. My buddy had three broken ribs from hitting the center console.
The cause of the crash was excessive speed and possible DUI. The kid (yeah, he was underaged) wasn't legally drunk when they gave him a blood test but there were cans of Four Loko (?) in the back. They also found drug paraphernalia. That wasn't the least of the issue. He damn near got his passenger killed. She was in a coma for months.
