Ty! The point about control and reachability makes sense, and sounds like it might be a part of the right story here. It will still need some tweaks or additions though. For example, we would intuitively expect that a self-driving car without any cameras or sensors isn’t entangled enough to do its job. But in terms of reachability, everything is still fine—the car could give the right set of commands that would get it safely across town, so the safe states are technically reachable.
