"things that move small numbers of people to exactly where they want to go" -- I can describe feet in the same way! My feet also work after drinking, they don't take up space, they gave me independence at a young age, and they provide health benefits (even the thirty minutes a day of walking needed to get to public transit and do grocery shopping makes a big difference over a totally sedentary lifestyle). A lot of that science fiction was written by Americans.
