If car designer Harsha Vardhan really believes that the Transport TW is the car of the future, he must have forgotten that some car owners like to park their vehicles indoors. While incredibly unique, this Tranport TW is highly unpractical unless smaller wheels are part of the plan. Even public parking facilities and fast food drive-thrus have roofs too low for the TW.  Theoretically, this single-seater would use magnetic fields to propel the wheels into rotation — operating in near silence.
