Public Transportation and Smart Growth

The short distance between each cart and each cart's short wheel distances combine to minimizes the effect of going inside, but each goes inside. People tend NOT to know that tractor Trailers are actually easier to drive and maneuver then a full size truck with a trailer. The reason is the short wheel base of the tractor, combined with the short distance to the trailer from the tractor makes it easier to maneuver in tight places, The shorter the wheel base on any trailer, the less it can go inside whatever is in front of it. If you look at this bus, each section is relatively short so that this effect can help the program to keep each wheel to follow the previous set of wheels. The short wheel base helps both a cart and this bus, but the real significance is the computer program that get the wheel to follow the track of the previous set of wheels.
