> Teslas autopilot can only be enabled in comparatively safe and simple circumstances
This is incorrect. FSD can be enabled everywhere from dirt road to parking lots, even highways and dense urban environments like NYC. There is no geofence on FSD, you can turn it on anywhere the car can see drivable space.
Does it enable in heavy rain or snow, on ice, fog? Does it work in storm conditions with leaves and objects blown over the street? Does it work in confusing traffic situations, invalid signage, …?
