Recently, one of my friends shared a video titled "The Next Generation of Transportation!". The concept depicted in the video led to a friendly argument among us. The main problem which the designer intended to solve remained unclear here. My reflect was that the design seemed to be a failed attempt to improve rail transport, by bringing in the concept of an aircraft. My friend liked the outcome as it had some superiority to both ground and air transportation. Comparing to airliners, this video shows a much easier boarding and deboarding experience.
