With a lot of sleek Yamaha concepts on display at the 2007 Tokyo auto show, Bobby stood out for its awkward look. This electric scooter is designed for commuters. It's not much smaller when folded up, but Yamaha points out that it can be more easily stowed in the trunk of a car or kept on a balcony. OK, we'll buy that. Bobby incorporates an RFID reader, so you can use a cell phone equipped with a Sony FeliCa chip as a key. The future is sounding weirder and weirder.
