It's hideous; I agree. The prevailing argument here for the covers is fuel economy (i.e. reduced drag). Show me the numbers with and without the covers, but, I'd bet they're not so different that I'd sacrifice the look of the automobile by adding them, especially considering the 250+ MPG claim here.

Small gains can add up. I had a 75 minute commute for a while and ran some MPG experiments on my truck. Adding a wedge shaped tonneau cover, a chin spoiler, and inflating the tires more boosted my MPG from 18-26. It was ugly so I took them off and got distracted before I built them again. It was much quieter and seemed to "roll" along at faster speeds.
