From a Yahoo News story about a 'test driver' (not sure if he works for the car company or was a motoring journalist) almost hitting a deer and it being captured on film. Can't view the video here...
"According to National Highway Traffic Safety Administration statistics, deer are responsible for or involved in around 1 million collisions with automobiles each year, killing 200 Americans, causing more than 10,000 injuries and $1 billion in vehicle damage."
I love the 'responsible for'. I know it's probably the most apt word to use, but it brings to mind the deer deliberately jumping out in front of cars!
