Belt drive and solid (airless) tires?

This is such a great idea for a congested, urban environment. Walk to bike station, take bike, ride to next bike station, deposit bike, walk to final destination. I guess you have to ride to another bike station if there are no empty slots to deposit your bike? But hey, you don't have to hunt around for a place to lock up your own bike, and hope its still there when you are done.

I wonder how they are going to integrate the safety-nanny state dream of helmet use? Or would this be where the nanny state finally admits that ordaining helmet use isn't worth it if there are other benefits or practicalities to worry about? Future legal headache for providing and even encouraging use of a product without providing for basic safety needs? Hmmm.
