Basic Autopilot that is free on every model is advanced cruise control + lane keeping.
FSDS (Full Self Driving, Supervised [for now]) can handle the vast majority of driving scenarios, from A -> B. I currently intervene once per 10 drives, usually due to a routing issue (never safety critical). It is rapidly improving, and will drop the human requirement once it surpasses most drivers.
FSD still requires you to pay full attention. The name is still a lie and Elon has been claiming the human requirement will be dropped “soon” for what now? Almost a decade?
