Sorry if this has been asked before but I couldn't find it with a search. I've had my model 3 long range with FSD for a few weeks now. I have been able to use autosteer and navigate on autopilot pretty regularly but I cannot enable the automatic lane changes without confirmation. When I go to that section of the settings it is grayed out with no message as to why, is there something else I need to do to get that to be selectable? Or could it a regional thing (I live in South Dakota)?
