I totaled my first car. Like, the car itself just stopped where the windshield met the dashboard. Ahead of that point, there was no more car. It was gone.
Me? I had some really spectacular bruises and a lil friction burn on my nose from where Mr. Airbag and Ms. Glasses had a disagreement. That's it. That's it.
I was driving a little tiny coupe and went more or less head-on with a pickup truck. The entire engine and hood of my car was twisted rubble that was not connected to the rest of the car afterward. I sat down on the verge, about twenty or thirty feet from the accident, while I waited for the cops and EMTs to work their way through the traffic backup to get to us, and found that I was sitting beside one of the headlights of my car. The whole entire headlight, bulb and reflector and cover and frame and all.
All I had were bruises and that little friction burn. That's it.
Crumple zones save lives. So do seatbelts and airbags; half the bruising was the exact shape of my seatbelt in livid crimson and black on my torso. It was and remains the most insanely intense bruising I have ever experienced in my life. BUT IT WAS JUST BRUISING!! Unpleasant, sure, but eminently survivable and didn't even require much treatment beyond not wearing a bra for a few days. But all the force that created that spectacular bruising was force that wasn't flinging me through the windshield or impaling me on the steering column. My car crumpled and crushed and dissolved but it held me safe and secure and protected.
Crumple zones save lives. You do not want your car to look undamaged after the accident, because that means it made like a Newton's Cradle and passed every bit of the impact straight through to your soft and highly crushable body.
