This year's ride showed us a few things,
First, it is possible to get over 200mpg sitting up, Go Vic

.
Second, even fully streamlined, riding style is still extremely important (read, I got beat by a less streamlined bike with a better rider.)
Third, electric bikes are here to stay. All of the crazy motorcycle guys in the campground were talking about them, and it was mostly in amazement. They had quite the discussion about how to classify electrics so you could race them against the gassers. And these are race guys, not efficiency nuts like us.
And finally, it is still impossible to park a streamlined bike without someone approaching to ask questions.
