You know you need this. It's only $35,000 and it's also the world's smallest co-axial helicopter. Buy online at: www.gen-corp.jp (Scroll to the bottom for a video)

From Odd Japan:

GEN Corporation developed GEN-H4, a compact single-seat helicopter. Equipped with a miniature engine of 125cc (8 horse power) and two propellers, it can reach a flying speed of 90 km (56 miles) per hour. At the moment GEN sells it at 3.6M yen and organizes demo flights as well as training courses (charged separately, of course).

With some skill it should be useful for commuting and avoiding crowded trains. To the Doraemon fans out there: I guess this is the nearest thing on Earth to "Takekoputa" (bamboo-propeller), what do you think?!
