Well, Mr. Day, the 2008 BMW's Gina concept car had a textile waterproof body that automatically adapted itself to changing aerodynamics conditions; truly logistical services depend less and less on trasporation only but - especially in overseas operations - on ship-and-make processes. When I hear that a huge airplane such as the Antonov 124 takes ten hours to fly an underground train from Germany to New Delhi (India) I simply think "what a waste ! why not a ship instead, ten hours or ten days what difference would it make for an underground train ?". In an increasing number of north european cities, people live and work there, they don't need to move by car, they byke or use streetcars instead. Auto technology is living on its own blood: if - ever - anyone will come up with a more clever transportation system, and i don't think the Chinese aren't so far away since their car industry is not so effective, the Indy's 500 miles will probably be run by hovercrafts. Man has invented the wheel but the wheel is not the only way to move people or goods.
