I wonder if that would really be a popular mode of transportation. (I know this isn't happening at Disney) I have no idea what the actual stats are, but I know alot of people are claustrophobic. It looks like it has pedals too, or am I just seeing things?
Ah, to be stuck in a small clear tube because some guy in front of you passed out due to exhuastion or from fear of tiny spaces. That will improve traffic.
