When is money ever OUT of the equation though? Never. Besides, the "ultimate engineering and technology" vehicle wouldn't even have wheels. Wheels limit travel to a two-dimensional plane (more or less). See: Space shuttles, rockets, jets. The ultimate in "wheeled engineering and technology" always seem to take after motorcycles regarding their relative width and aero principles- they just add more rubber for additional contact patch. See LSR holding vehicles, streamliners, and Top Fuel dragsters. I would bet you there's more money and engineering involved in making a car go 400+mph in a straight line than an F1 car turn around a course.
