I'm not saying that the spoiler is "safer", I'm saying that ANY physical change, such as the presence or non-presence of a spoiler, that alters the dimensions or the profile of the car, could potentially require an entirely seperate set of tests and declarations and paperwork. It's no different than the silly fact that if you just change the gear ratio in a car, the whole car has to be re-certified for EPA, which is why U.S. automakers shy away from offering choices of gear ratio.
I thought the moose comment was totally silly and innocuous. If you believe that to be an insulting "cheap shot", good lord......you're easy to rile. Yeah, it's a forum, but my "cheap shot" was the equivalent to joking about a tumbleweed catcher option for Texas Mustangs. I seriously doubt that somebody from Texas would come firing back, "hey mister, that's a cheap shot...sniff, sniff...
". Typically down here in 'da south, it's the dumbass rednecks who are hyper-insecure and overreact at the slightest poke of fun (now THAT'S a cheap shot, just a more subtly cloaked one). I'm sorry about the moose reference. Feel free to joke about alligators, or opossum, or cockroaches, if the redneck jab didn't satisfy enough. A good sense of humor can really help your blood pressure.
