In over 25 years of driving, I had never hit a mammal on the road. I have collided with 2 birds that swooped down. While I feel bad about that, there really was nothing I could have done. A few times over the years, I have taken full advantage of the handling limits of the vehicle I was driving as well as unique possibilities offered by the situation to avoid hitting something.
As I was driving down the highway, a bunny rabbit suddenly darted from the side with perfect timing as if he was trying to commit suicide. Had I been going the speed limit like I should have been, there would have been an outside chance of avoiding him, but even then it would have been tough. I did my best, but it wasn't enough.
