Paul Graham wrote a while ago about the "Trouble with Segway" http://www.paulgraham.com/segway.html He writes:

"The Segway hasn’t delivered on its initial promise, to put it mildly. There are several reasons why, but one is that people don’t want to be seen riding them. Someone riding a Segway looks like a dork."

The obvious problem with the new transportation capsule is that it makes you look like a cockroach in a glass jar.
