itty bitty bunny brains

I got hit by a bunny last night. That's right, it hit me.

I was driving through Scottsdale, Arizona around 4am. I'm headed down a divided road with a lot of shrubbery in the median. Suddenly I hear a loud BONK on my door. The car doesn't shake or bounce or anything, so I'm wondering what happened. I glance in the rearview mirror and see a bunny butt running away from the car.

I'm wondering, was it an inept jackrabbit suicide, or was it some psycho rabbit headbutting my car?
