My bet is on Google Glass going the way of the Segway... ...that is to say, ridiculed by the general public, but finding a bit of a niche in certain industries. The police, postal carriers, etc. @cstross did a pretty good job of convincing me that some form of augmented reality would be very useful for the police. There is a real-life push right now to get police wearing cameras too, I think this sort of device could…
"IT" can go up to two hundred miles per hour, gets three hundred miles to the gallon, and is an all-around better mode of travel. The only problem is that "IT" is controlled by a quite painful and uncomfortable method; using four "flexi-grip handles" that somewhat resemble erect penises; two held in the hands, one in the mouth, and a fourth handle which is inserted into the anus. It also transpires that the vehicle can be operated with buttons too, making the phallus-like controls an unnecessary discomfort. Garrison invites many important investors such as Bill Gates, Steve Jobs and Yasmine Bleeth to see how "IT" works. Despite this unorthodox control mechanism (which is uncomfortable to the citizens of South Park), "IT" is still considered better than the airlines and Garrison is a smashing success.
