Driving cross country in a car is actually the worst when you're in stop and go traffic, or cars keep slowing down and then speeding up. I can't wait to get my hands on adaptive cruise control because I get so aggravated and tired from having to shift and adjust speed. If I can just sit in one position and listen to comedy podcasts and audio books I do so much better
I finally got a car with adaptive cruise control and lane assist a couple of years ago. It is the best. Driving feels relaxing. I actually feel less fatigued. I can just listen to music /podcasts /audiobooks and not care about how others are driving. Feels like sitting in the passenger seat and watching the road.
I wouldn't feel safe if I wasn't listening to something that kept me engaged though. I would totally nod off.
I don’t have good “lane centering” but knowing that it has the lane departure warning and will automatically bounce me back into the lane if I slip up for a moment is enough to make driving less stressful.
I was excited to get adaptive cruise control, but I’ve found I don’t like using it very much. It’s too aggressive with hitting the breaks to maintain the following distance instead of being able to ease off the gas to fall back like a human driver would. Assume some brands are better at this than others, but anyway I didn’t buy a Mazda to not drive it. So I use that only intermittently for long drives as a bit of a break for my right foot.
