Folding Bike Handlebars - Where have these been??

Another one for the why-did't-I-think-of-that file - or, for that matter, the why-haven't-these-been-around-for-decades file - these are folding bicycle handlebars, from designer Joe Wentworth on Tuvie. These offer a number of improvements over the solid handlebars of, well, every existing bike: the bike will take less space when leaned against a wall, less space when crammed into a trunk or SUV, and the folded handlebars will lock the steering so the bike doesn't roll-and-fall like they tend to do when leaning. And, as Gizmodo writer Sean Fallon notes, no more "groin-first trips into my exposed bike handlebars." All the more reason these should have been around for decades!
