SCIENCE!!! It turns out the University of Tokyo has just completed a study which confirms people who ride motorcycles on a regular basis have higher functioning brains than their caged-transportation counter parts. Even more interesting, some other studies that were done suggest that even thinking about riding can improve brain fuction. Take a look at the article here. It's actually an easy read, but then again it may only be easy for me since I'm so much higher functioning than you are.
