Radar doesn't have resolution to identify cars per say. Radar "paints" a rough picture of reflective objects that are moving relative to you. For instance a swarm of birds can look like an airplane to radar.Does the nearby cars visualization on the Model S instrument cluster use radar at all or is it based on cameras only? I feel like it's gotten worse recently on my Model S Refresh (with radar hardware, 2022.16.3 firmware). But it's possible it was a software regression or I'm imagining it (it always was a little finicky).
