I've done plenty, I'll hit the highlights here.
When I was 16, rearended someone brand new car that he had bought that week. What kind of place was that for a stop sign, anyway!
Crunched up my bumper, but really did alot of damage to his car.
Again 16, backed into a friend of mine's car pulling out of a driveway. Just a dent which was easily fixed.
When I was 17, pulled out in front of someone. Fortunately the speed limit was only 35. This time, it was their bumper crunched. My car was rather smashed on one side.
Again, when I was 17 on the way to school pulled out of my driveway in front of an 18 wheeler. It just hit the front and took the bumper right off. Fortunately I wasn't a couple of seconds sooner pulling out or it would have smushed me for sure.
20, smashed the back end of a car that had stopped to turn left. What was he thinking turning there?
Messed up both cars.
Believe it was my 22nd Birthday, I backed straight into of friend's ditch. It had to be pulled out of the ditch, but no real damage.
When I was 23, I was on the way home at night from a case about 2 hours from home. My company paid for my hotel to work there several days in a row. I could have stayed that extra night, but wanted to go home. Have always wished now I had stayed. Anyway, it was raining pretty hard, but I was still going at least 70. I hydroplaned and lost control. My car turned around in so many circles, and then I ran off into a ravine. Pretty scary! Broke my nose on the steering wheel~ouch! Don't know why the airbag didn't work.
I plan to never again have anything to add to this thread!
