I think too much focus at Tesla is on FSD beta while barely anything trickles down to standard cars. They need more developers who extract new features down and make them ready for a worldwide rollout. The best symptom of this is the horrible state of Auto Pilot in Europe. Or how their auto blinding lights are just outright bad even though they have all the tools to fix it with a nice update.
Autopilot is terrible in europe because of EU laws. Driver assist systems in the EU cannot impart more than 3 m/sec^2 of lateral acceleration[1], which means they're useless for many turns. Another restriction is that lane changes must be initiated by the driver and they must abort if the lane change has not succeeded after 5 seconds.[2]
