Hi Alan - you and me both! It seems the "Find My Car" function isn't actually intelligent at all. It relies on you telling the app where "you left it" and then if need be, you can ask the app to direct you back to it. Such a shame, other countries get a myriad of clever services in their connected apps - like starting the engine, warming up the cabin, closing the windows, locating your car, checking tyre pressures, etc etc - and we get...... er, nowt. 😞
Cheers
Steve
