I have a 2018 XC60 and it's been really great on the whole, but very clearly Not There Yet™:

+ During a dark and wet night a few weeks ago, I used Pilot Assist (lane/speed/steering control) and it genuinely saw the lane lines better than I was able to during major unexpected downpours. I was in control the whole time, but it was a great help along the way and made the drive a lot more comfortable.

- Some of these systems work together rather poorly. For instance, the Pilot Assist system seems to identify white lane lines better than yellow ones, and on US highways (where the left-most edge is often yellow) it will drift left. However, the lane keeping system seems to see the yellow line just fine, so it will vibrate the steering wheel to warn that I'm getting too close, while Pilot Assist continues to insist on moving left. The solution is to get out of the left lane.

But I'm very optimistic and supportive about Volvo's trajectory in this area, to all of your points above.

Oversharing: I've been driving a Volvo XC90 with Pilot Assist and a Tesla Model 3 with autopilot. Of the two systems, I really preferred the Volvo -- but not, ironically, because it was better, but rather because it's worse.

The Volvo's system is very clearly about 70% there. Sometimes on sharp curves it just misses the lines and drifts into another lane. Sometimes it seems to basically just follow the car in front, which means that it will blindly follow a bad driver in doing stupid things. However, the upside of this is that its weak behavior (and willingness to yield to driver input) makes it so obviously an "assist" system that I would never really put a lot of faith in it, or trust it entirely. Thus to me it's just sort of a better version of the lanekeeping system.

The Tesla, on the other hand, really wants to drive the car. It hates taking feedback from me, and will often boot me out of autopilot mode if I disagree over, say, my position within a lane. It does a much better job seeing lanes and handles lane changes automatically. But: because it's so forceful and doesn't like my input, I find it much more stressful to drive. I don't trust it enough to let it have the absolute control it wants, and find myself missing Volvo's pretty-dumb-but-not-demanding system.

  Sweden has such things as constant low sun, snow, rain, sleet, active wildlife etc. etc.

California has those things too depending on geographic area of the state.

They've also set trucks that can reliably drive around private roads, mines and loading zones without having to handle much in the way of novelty or people as a practical near term goal they'll probably make a commercial success of even if fully autonomous cars are decades away or incapable of ever being viable for regular unsupervised road use.

Obviously it helps that they're already a leading truck manufacturer, but it's interesting to note how many other ventures have gone for the "eliminate the taxi sector and reinvent car ownership" over the low hanging fruit for [semi]-autonomous vehicle markets.
