With the caveat that this could certainly be my imagination since I haven't driven nearly as many miles recently, it seems like the 12.1 update (or maybe it started in 12) changed the driving dynamics of autopilot. Particularly it feels like lane changes "feel" different than before. They haven't slowed down how quickly the lane change "starts" after you engage the blinker, but it it seems like the the amount of time it takes to complete it is noticeably slower/smoother. Since the "lane change" improvements last fall, the changes happened really assertively. I feel like they've recently made them more natural. I also noticed since 12.1 I've had 4 or 5 lane change aborts which never happened in recent updates. For reference I'm on HW3. Any one else notice this? Or my imagination since my volume of driving has gone down so much?
