One more reason why the prevalence of cell phones can be useful and exceptionally cool: in Germany, you can rent a bike with one. Just dial up the Call a Bike service when you come across one of their bikes on the street and they'll give you the code to unlock it and bill you for as long as you're using it. Call them a second time when you're done with it and the bike will lock back up and they'll stop charging you. One might think this system would be pretty prone to security issues, but it's still a damn cool idea.
