The version of autopilot that came with my car is essentially adaptive cruise control + self steering. If I need to change lanes, I signal and it disengages the steering part but the adaptive CC is still on. Also, even if I'm not using AP, lane keep assist will kick in if I start to drift out of my lane without signalling first.
Automatic lane changing is NOT included and neither is navigate on AP. I have to get FSD to get those features.
Not sure how that compares to the old EAP. Hope that answers your question.
