The Transport TW has only one giant wheel and the cockpit is comprised of a singular swivel seat with a rear door.
The Transport TW would not only be eco-friendly in the real world, but this form of transportation would also probably be very smooth with virtually no noise.
Implications - But not only that, can you imagine riding side by side with a fellow motorist on a highway full of these things? It would totally look badass! Though car accidents involving these futuristic contraptions may look quite gruesome.
