It had certain fail-safe modes when critical failures occurred. This would inevitably involve what was called an Open Loop Pull-Up....a 3-4G pull up with a gradual disengagement of the autopilot. Not the sort of thing you want to occur in badlands.

Very effective, I totally trusted it. Used routinely on the Gr1, less so on the GR4 due to it's NVG/FLIR capability. Yes, it was truly hands-off and it could either follow the computer demanded route or you could manually steer it using the heading bug on the pilots HSI. It was usually reliable, though in the early days of the GR1, less so. It could be used in hilly terrain though had natural limitations the steeper/higher the terrain became. Worked well over all but the calmest of seas and had a back-up if the radar could not see the surface.
