Is a self driving car aware of itself? Surely within its logic it represents itself as a vehicle, while also being able to logically represent other vehicles on the road. Its logic accounts for there being similarities (they both obey the same laws of physics and such) and differences (its logic controls its own behavior but not that of other vehicles). So it has a meaningful and useful concept of "self". All of this is required for it to be able to function.
What if some future iteration of a self driving car's vision system allows it to glean useful information from reflections, such as off of store windows? If it correctly can identify a reflection of itself as being itself... well then it has passed the mirror test. But that is a pretty silly thing to assign too much meaning to.
I just don't see "awareness of self" as being meaningful. It doesn't narrow down the definition at all.
