Had a deer bolt out of a neighbors yard last year. There were 3 of them, blocked from my view in the side yard. I saw a flash of brown just as I went behind a van that was parked on the street. Thought it was a big dog and prepared for flight because he had the angle on me. When I rolled out from behind the van I saw that the little buck was headed toward the street and my Momma's little boy! Scared the bejeezus out of me. Jumped on the brakes hard and avoided a crash...barely. Dunno what made him bolt. My front blinky maybe?

There was a u-tube showing a guy getting mowed down by an Impala. (four legged, not four wheeled) Looked pretty bad.
