> is the human+self-driving system really better? Definitely. My last couple vehicles have had Lane Keep Assist and Adaptive Cruise Control. I believe those two equate to about "Level 2" of autonomous driving. Whatever the technical definition is doesn't matter though, the important point is that those two features alone make driving long distances so much less mentally taxing. The Volvo system in particular is great... keeping your vehicle firmly in the middle of the lane like it's on rails. Frankly, it's better at that task than I am and only requires slight and occasional steering wheel input to stay engaged -- just enough to know you're paying attention. Before these systems, I'd be mentally exhausted after driving 2.5 hours to my parents house, especially if there was stop n go traffic and it took even longer. Since these systems, I arrive feeling mentally refreshed instead of drained. There is no way I'd buy a general purpose vehicle without these systems ever again and I look forward to any other ways that automated systems can augment my ability to drive safer, more precisely and with less effort.

ACC and Lane Keep was incredibly awesome when I was driving at night through northern Ontario. I was able to focus 80% of my attention scanning the ditches for moose and other large critters.

  I crossed into BC from Idaho at night a few years back and shortly after noticed a LARGE animal off the side of the road. Pretty sure it was a moose, but it may have been an elk. Either way, I spent the next few hours paying extreme attention to the sides of the road. It made the drive much more stressful and having a little backup would have made a huge difference.

I relax more on longer drives with ACC. I tend to drive faster, so slow drivers in the left lane drive me a bit batty. With ACC on, that tendency is blunted heavily, and I just roll along, making occasional adjustments. But my temperament is much improved.

Agreed. I did a 1,500 mile (2,400 km) round-trip drive from Los Angeles to Utah a couple weeks ago using these same features in my Tesla Model 3 and it's a very different experience from previous trips in other cars.

LKA and ACC are two separate level 1 features. LKA is lateral and ACC longitudinal only. A lane change assist which speeds up and steers to the other lane is level 2.
