Got my update notification last night and installed this morning. Didnt really notice much with the nags, but I was always in the habit of randomly wiggling the steering wheel while on AP before even getting a nag, or placing my hand on the steering wheel like so...I dont actually move my hand, but there is enough friction/resistance as the wheel makes adjustments on the road that it keeps the nags away.
Couple other things that seem new, though not 100% sure...
1. When you turn on Autopilot, the lane lines turn blue but not instantly (as in instant gray to blue), its like a gradual "power up" type of visual. though very quick.
2. When not on AP, the car in front in your lane is a dark gray color, but once you turn on AP, the car is highlighted white - was it always this way?
