The people mover is automated. It doesn't have a driver. It is powered by a system that cannot be driven over by other vehicles. It is not compatible with other ground vehicles. The people movers technology requires it to be grade separated. The technology is not compatible with standard street car controls and cost far more than a standard street car.

It would cost far more to extend the people mover than it would to install the M1 type system due to the requirement of grade separation.
