That's an oversimplification of autopilot systems. They can follow flight routes, avoid traffic (TCAS), even auto land to name a few.

Auto-landers are not simply classified with autopilots. An autoland system is an advanced function that is part of a modern aircraft's overall autopilot capabilities. A basic autopilot can control an aircraft's attitude and heading, but an autoland system can automatically execute the full landing procedure.
