They have pretty software that is shit. I don't own a Tesla, but whenever I ride with friends the center console shows an overhead type view of the other cars around. The cars randomly blink in and out, indicating it doesn't know if the other car really exists or not. A cars UI has has exactly one function: provide accurate and actionable information to the driver. You should never need to second guess the information you are receiving.

Pretty much every company that tries to capture the environment around it uses a probabilistic model that takes in the raw sensor data and makes predictions about things in the surroundings. The random blinking you see on the Tesla screen is essentially saying that Tesla's model prediction confidence is borderline and changing from instance to instance. Is that great? No, but they can't do much using just vision data. What's the alternative? Show the cars even when your model is not confident anymore just for user experience reasons and give false sense of confidence? That's not ideal either. Imo I don't know any other consumer car company that shows anything like that on their cars infotainment console. Companies like Waymo and Cruise do a much better job at capturing surroundings but they are in a different market where it makes sense to spend a ton of money on each car to add many LiDARs and significant compute in the car.

The wild flickering of lines, obstacles, humans and cars in perfect clear daylight conditions is absolutely flabbergasting to me and erodes any trust I have into self driving capabilities. It's outright scary.

  You are probably talking about autopilot, not FSD beta which is entirely different stack. Cars that are running basic autopilot show basic autopilot visualizations.
