+Get in a golf cart and drive backward. The camera feed replaces the map on the
+cart's GPS screen, mirrored like a real backup camera, and the map comes back
+shortly after you stop reversing. Rear lights also turn on while reversing so
+the camera can see at night. If a cart has no GPS screen, the feed is shown at
+the bottom of your screen instead.
+
+The rear lights and camera are only visible to players who have the mod.
