Here's an interesting concept vehicle that incorporates pedal power.
It seems like it would be a very popular alternative to a commuter van, or maybe even a city bus.
Of course, somebody would need to be the designated driver. And if there were a jovial fraulein to keep the brewskis comin', it would likely have a positive impact on average speed.
(There is a little-used railroad line between Boise and the bedroom communities to the west. Perhaps this thing could be retrofitted to run on tracks. Leave Boise at 4pm with a full keg; arrive in Nampa by 5:30, keg dry and passengers feelin' no pain!)
