No More Gas Caps?

I'm sure it earns me another 15 minutes in purgatory, but I can't help laughing at folks I see driving down the highway with their car's gas cap cover open. I've never understood how you someone can replace the gas cap, but not close the cover. Being easily distracted, I can understand forgetting both. But getting one and not the other?

Anyway, not sure how this will affect those forgetful folks, but I see where Ford is eliminating gas caps altogether. They're going to a NASCAR style filling system.
