Crate and barreling down the road

Under what circumstances would anyone think that putting a dog in a cage on the roof of a car for a long trip is a good idea?

Mitt Romney apparently thought so back in 1983 during a 12-hour family drive from Boston to Ontario. Sure, there was a shield of some sort but it must have been terrifying for the animal.

I don't even like to see people allow their dogs to stick their heads out the window. Look at your front grill or windshield sometime. That stuff can get in the dog's eyes.
