I’ve had similar issues. Car keeps changing lanes when it does not make sense. Or fights me about what lane to be in. I’ve stopped using NoA because I spend more time fighting it than receiving benefit.
I’ve also had NoA try to turn into reverse direction HOV lanes with gates closed just a hundred feet or so in front of the vehicle at 70mph. Terrifying.
In a situation like that, I'll just turn NoA off. I mostly only use it on the two lane freeways in light traffic areas in the middle of nowhere right now - I haven't been impressed with its choice of strategies in heavier traffic or on roads with lots of lanes.
But I'm sure it'll learn over time. It might also learn to be a little less scary on exit ramps at some point.
