I’m in a park. The grass is being mown by a robot.

We thought the rider fell off or something and it was going to crash. Then it turned and kept mowing. Park Roomba!

You in the US?
Robot lawn mowers are very common in Europe. You'll see these small electric mowers in people's yards all over the place. Businesses also have them running all day out front. Never seen one in the US.
They are equipped with GPS, so they are locked to a specific area to prevent theft.
GPS are very fancy ones, unless that's changed since I last looked into it. A buried wire, "invisible fence", has been the norm for all consumer grade ones I've seen.
That's the style we have as well. In addition to the wire it also detects if it bumps into walls.
