Was watching the boob tube and caught a commercial for a new episode of Mythbusters with something interesting... It looked like some sort of streamlined motorcycle.
Looked it up, it's an episode called Bikes and Bazookas:

There's some footage of their streamlined bike on that link.
The premise seems to be testing whether cars or bikes produce lower emissions (I presume this is a question because bikes have better mpg but less pollution controls). Looks like they put it to an "ultimate" test by streamlining a bike.
However, to me it seems they add a TON of frontal area in the process. I've never seen a bike on the salt flats that looked like their creation...
Of course, no results at this point. Ya gotta wait for the episode to air later this month.
