> I'm curious why more of the autonomous driving tech isn't being used in what I might have thought would be an "easier" place to do it.

There's no real need in a static environment, and much simpler ways to do it. Children's toys can follow a line painted on something; they just need proximity sensors and a basic signalling system (RF or also painted on the road) for where to stop and done.

There's no real need for the car to "see" beyond "am I going to run into something" and they operate at speeds where stopping is very feasible.

They're also a bad rival for light rail because they already have to dig a tunnel and the conveyance operates on a fixed path. They picked a domain that light rail is already incredibly good and efficient at.
