Some might consider it a feature if the glove box needs some known-only-to-the-owner quirk to open as basic security, at least prior to having voice/phone activation as an option. As i understood it, the valet mode is an early preparation for autopilot ride-hailing activity while the owner is working, otherwise known as robo-taxi mode, in order to keep the compartment locked in non-privileged cases. Can any owners confirm this?
Valet mode is a common feature on luxury cars; prior to the fancy infotainment stuff, it was a valet key that wouldn't unlock the glovebox or trunk, but would drive the car.
