My car has lane centering and radar cruise control. I use it frequently on dry, well-marked highways. It allows me to drive with less mental energy because I don’t have to steer the car or maintain speed. My hands are always on the wheel and I’m still watching everything as if I was driving. It does a good job under ideal conditions. This may not seem like much but it adds up over a multi-hour trip. In rain or snow, I tend to avoid any automation to keep continuous awareness of how much traction my tires have. Too many people have died when automation hides problems until failure and then squishy thing behind the controls gets surprised.
