Specifically Auto Pilot is lane keep and traffic aware cruise control (it will slow down if you're going faster than the car in front)
FSD adds auto lane changes (it can do it by itself or the driver can initiate with the turn signals), makes turns necessary to follow navigation. It does a pretty decent job on freeways.
That they are working on now is getting FSD to work better on city streets and secondary highways
