Just completed 15 miles on 10.5 from an urban center to my suburban home. No disengagements, just 3 or 4 instances goosing the accelerator to deal with hesitation or unnecessary slowdowns. The car now mostly stays right of center in my neighborhood when there are no cars parked on the road, which is a significant improvement.
Unfortunately, it can still end up blocking the opposite side of an unmarked road when creeping forward after turning the steering in preparation for a left turn. At least it starts the turn from the correct side of the road and it's no longer playing chicken with oncoming cars on neighborhood streets. That's enough improvement for me to use it in many more situations.
