Mine definitely changes lanes on its own with my hand resting on the wheel. No additional confirmation needed.
Now if they could just add some settings to turn off or adjust how often it gets out of the left lane it would work better in my opinion. I feel that the car is changing lanes way more than I would and I end up turning it off. It should look further down the road to see if getting out of the left makes sense. Instead it moves me over (no one behind me) and then I am up on a slower car 30 seconds later and it puts me back into the left again. Too much bobbing and weaving.
Patience. It'll get there. Remember where we were 6 months ago, and think about where we are now.
