Adaptive cruise control is automatic speed adjustment, with you doing the steering. This adds automatic steering and removes the need to keep your hands on the wheel. Hands-free is the big differentiator from existing lane-keeping systems.
Personally I could care less about automating driving on surface streets. I'm a fan of just about anything that makes the long hauls easier.
The Ford thing is "hands in your lap," and is publicly advertised that way. It's far rarer.
From the article: “…become the first to offer hands-free driving capabilities on roads in the UK – a first for the whole of Europe, as well.”

"To be clear, HDA 2 is not a hands-free driving system. If the driver takes their hand off the steering wheel for several seconds while HDA 2 is active, the system will warn the driver with a message in the instrument cluster that reads, "Keep hands on steering wheel." If the driver keeps their hands off the steering wheel, the message will reappear with an audible warning. After the second message, if the driver does not take hold of the wheel, a new warning message will appear, and the system will deactivate."
