+ 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.
