extomesm, bikes like that are meant for races where you aren't allowed or able to draft your opponents, such as a pursuit where two people start on opposite sides of a track and the first person to get passed loses; or an hour record where you see how many laps of a track you can do alone in an hour. Basically you sacrifice some ergonomics for aerodynamics. For the same sort of reason, triathlon bikes look really weird---triathletes aren't allowed to draft each other and so they set their bikes up to fight the wind.
