ACC with LKAS is not the same as "you don't need to keep your hands on the wheel". AFAIK, It's only GM (Super Cruise), Ford (Blue Cruise) and Mercedes Benz (Drive Pilot) who have ACC systems that are designed to be completely handsfree on select motor ways.

"Don't have to firmly grip the steering wheel" is a thing. You're supposed to keep your hands loosely on the wheel, following along while the car takes the lead on turning the wheel.

The Ford thing is "hands in your lap," and is publicly advertised that way. It's far rarer.

Very few in the US (the MachE mentioned in the article is one with BlueCruise, SuperCruise from GM exists as well) and only one in Europe.

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.”
