Your thoughts on lane assist?

Lane assist on other brands will shunt you to the left or right. The Volvo one does not do that. It tries to fix your course to maintain you within the lane but it does not shunt you in any way.
If you continue to overtake the lane it will warn you by vibrating the steering wheel but it lets you go off lane if you want to. Other brands like VW will actually do a lot of force on the steering wheel to keep you on the lane.

Yes, vw lane assist, at least in a Tiguan we had as our second car was effectively an ‘always on’ pilot assist, and for me, worked better than the volvo system which only really corrects gross deviations from course. Combined with the ACC the system was like (I’d even say better than) pilot assist. I also like the way the system operated independently of throttle so was much more useful in controlling/ setting course in far more circumstances than when I feel safe to hand everything to PA

Not comparable at all with an "always on" Pilot Assist since it's not able to drive the car. With Lane assist and AAC from VW you have an autonomous driving level 1 while with Volvo's PA you have autonomous driving level 2.
I have used Pilot Assist successfully on mountain roads, although is not recommended due to the lack of adjustment of speed, but I did it for testing purposes and it worked, sometimes doing aggressive angled curves. This is something that the VW system is not able to do. It just corrects the trajectory of the car but it is not actively driving the car and you need to keep your hands on the wheel. If you perform the same test even with no curves, you will definitely crash on a VW car.

Well - having driven many thousands of miles with both I’m not sure i’d agree that the real world capability of the two systems is all that different. PA2 (I’m yet to try PA3 properly in the MY21.5) would also lead to a crash very quickly on a typical sinuous UK A road with no hands on the wheel. These are motorway systems really.

The most recent lane assist + acc on the VW MQB platform will quite happily steer the vehicle and place it within a lane on straights and moderate curves, traffic crawl etc - it also displays exactly the same trait as PA - namely giving up very quickly with no real warning often in a bend when realising it’s run out of ability mid-curve.

Maybe you experienced a faulty PA because it does not make sense to compare a level 1 with a level 2 of autonomous driving.
If this was a standard and if there were doubts, what SAE defined back in 2014 regarding the autonomous driving requirements would be completely discredited.
