PHYSIX OBSERVATION

This upgrade pushes the car-control app from a remote on/off tool toward visual interaction. The 3D car model and arrow car-finding improve the car-locating and car-viewing experience, while high-temperature protection hits the pain point of summer parking. But the features depend on battery level and network, so the actual experience still needs verification, and it also shows that automakers' competition in software services is shifting from feature quantity to detail refinement.
