I think getting out and leaving the car is the only way to fully reboot the car. There have been other issues where restarting the MCU (main screen) is insufficient. But I would think there would be a button in the UI to do a full reboot. But maybe they don’t want you in the car while that happens. One thing that is fun is how the car is still drivable (and Autopilot/FSD still functions) when the main screen is force rebooted while driving. The Autopilot and car computer are separate from the actual UI computer. So you can be mid reboot while the car is autonomously changing lanes, but the turn signal sound effect isn’t playing because it goes through the audio system which is rebooting. Good for safety that it works this way and doesn’t just stop driving, but can be quite an adventure.
