Zoom out on visualization when changing lanes?

2023 Model 3 with HW3 and Ryzen, but no FSD. A couple of weeks ago I suddenly noticed the 3D visualization would zoom out when changing lanes, showing much more of what was behind me. Fantastic, must have been a recent update, I thought. But it seems to have gone away after a few days. Could this have been a glitch and something only ever meant for FSD owners? Frustrating if so, as this is such a useful feature!
