Well, not always hands on wheel. I have spent over an hour straight on an interstate with hands off. Ford's system watches your eyes and lets your hands stay off if it's decent conditions and on a LIDAR-mapped freeway. Note I wouldn't trust it at night (there have been two crashes, both at night with stopped vehicles on freeway), but then I wouldn't really trust myself at night either too much (there are many many more human caused crashes at night, I'm not sure a human at freeway speed could avoid a crash with a surprise stationary vehicle in middle of the road).
