But the thing is, all the parts of the car DO NOT in fact lack the ability to move - because all the individual molecules and pieces CAN AND DO in fact move through space already. It is just that they can't move AS A UNIT.
So the systems theory problem for the car, is really just analogous to solving the combination problem of pansychism.
But it still remains absurd to believe that individual particles can produce sentience if they themselves don't possess the capacity for sentience. And the question, then, is just how multiple particles can act as a unity to produce a larger sentient perspective than the individuals.
