How will the pod cars at Heathrow fit in with this?

Driverless trains have been running on the Gatwick monorail for
years.

IIRC it has a bit too many rails to be a monorail. But aren't the two
tracks both elevated and completely separate, so the trains can't
crash into each other or stray cows?

Yes, it's a simple system (currently bustituted, of course). Presumably
there's some sort of points mechanism to get the vehicles on and off the
running tracks, but that would not happen with pax on board. Lots of
airports around the world have similar systems, and many do have
switches that are traversed in service.
