Seriously? I bought in-car navigation for my car instead of opting for CarPlay/AndroidAuto for this exact reason. When I start a trip, my phone (always used Google Maps) can never figure out which way I am facing and will keep rotating around and recalculating directions until I gather some speed on the road. With my in-car navigation, the compass works flawlessly even in parking garages and basements. I though the holy grail would be a UX where Google Maps would use its maps, traffic and navigation data while using the car's GPS.
