I always looked at it like this. If it doesn't have a license plate on it's arse, it doesn't belong in the street, and is fair game. I would never intentionally run over a dog, but nor would I run off the road and run over a mailbox to avoid one, either. Once a driver in my center parked in front of a house, jumped out over his seat to deliver a small package and when he did, he brushed against some kind of plant that mr yard of the month had growing. The little limb broke off, the customer called and complained, and the center manager said if the man's plant died, they were going to charge the driver with an accident. That's crazy talk.
