Yamaha 's R&D- concept bike

[F4celess]

I like the sound of that, you could save loads of space as there could be allocated parking in your street or tower block you get out at your door and then the car buggers off to its space BUT it only needs i inch either side as all the cars parked together no one is opening the doors. 

Infact the rear doors are ("Falcon") up and over (Lamborghini style), while the front are conventional side opening (bashing)!
