I'd very much not want to be in an airplane whose landing strategy was "automatically apply the brakes". Navigating to an airport, lining up with the runway, and gently bringing down the plane seems significantly harder than auto-breaking.

Garmin Autoland is much more than "apply the brakes", as I understand. But it's still guiding your plane through an essentially empty environment, not something in the same ballpark as autonomous driving.

Well, more or less, the "apply the brakes" system still has to detect obstacles and calculate the optimal way to brake and so on. So it has to deal with dynamic environmenrs. Autoland, not so much.
