As of Dec 2022, with FSD, still constantly "moving out of the right hand lane" on non-expressway 4 lane roads (2 lanes each way), with no one in front of me in right hand lane. I no longer use FSD with anyone else in car on the non-expressway 4 lane roads, since I am constantly fighting the system. I have speed set to 10% over speed limit. As others noted, the action occurs even when someone is approaching from behind in the left lane. The larger issue is that the car tries to automatically move to the left lane, and I have to cancel using the turn signal quickly to stop the action. I always use the setting whereby I have to confirm the lane change, which works on expressways, but the car changes lanes without confirmation on non-expressway multi-lane roads. The car should not change lanes without my confirmation, but it happens all the time with both "moving out of right hand lane" and "changing lane to follow route" (when a lane change is not needed for many miles or never). It is a bug, not a feature, not related to exits, merge lanes, or other excuses. In my Model Y, I have been dealing with it for 20,000 miles over the past year. I have announced "Bug Report" more times than I can count. I keep hoping it will be fixed with next update. I am hoping someone at Tesla looks at these forums. (I still use FSD a lot, including Miami to Seattle round trip and 3 round trips from Miami to Maryland thus far in 2022, but keep hoping the system will improve more quickly relative to fixable issues.)
