Once a software update is available for your car, the car will automatically download it when you are connected via WiFi. Once the update it downloaded, it will notify you on the in car display and on your phone an update is ready to install. You can then either schedule a time when it should be installed in the future (e.g. middle of the night), click to start the install immediately, or ignore the update for as long as you want. When you click to install, it begins a 2:00 minute countdown timer which allows you to cancel before the install starts. It says very clearly how long the update will take and that it can’t be canceled while it’s installing. You cannot drive the car while the update is running. If someone missed their dentist appointment because of a software update, it’s because they intentionally ran the update just before needing to use the car.
