I wont go through details but I have almost went through one windshield as a young teenager, and I was hit by a van at work when I first started in the utility industry. Neither one was a nice experience.

Other than that I hit a dog doing 65 (he was one of those Great Danes that was about 4 foot high) and done about $2,500 worth of damage to my Mom's car. I didn't even have time to tap the brake before I made him explode. If he lived I was going to stomp his ass out as I was so mad after it happened. We had to claim she hit a deer as I wasn't on the insurance yet
