Many marine autopilots integrate with AIS, sonar, and charts for accident avoidance and alerts. For example on some larger ships it is able to calculate if at the current speed a collision would occur and reduce speed to avoid it. Some can do "port to port" auto-steer, taking the vesicle through narrow channels.
We are both accurate. I was talking about boats, not ships. My point still stands - ships are required by Collision Regulations to keep a lookout at all times. And yet they are called "autopilots". Even the most crude of devices that I described (that is used on pleasure boats).
