Well, the thing is, while not addressing the apparent intent of your question, that with the “mind” as a particular form of self-referential processing based on physical materials it does have to have some physical influence by that processing. Which is to say that if I intentionally perhaps start to think sad or happy thoughts, neurochemical processes can shift where I now start to feel happy or sad. An element of method acting, using your mind to create the emotions or feelings within yourself that you want to portray. Exactly how much of what physical changes occur is probably more to your question (like the car parked in your driveway question) but a mind based on physical properties is going to have physical consequences, particularly in the self-referential and self-influential processing. Again not exactly what you were asking but a physical material based mind has to exert physical and material influences as well as respond to, being dependent entirely upon, them.
