Tesla has four modes of "self driving"--Autopilot, Enhanced Autopilot, FSD, FSD Beta.
AP/EAP will run red lights and can't merge lanes on a freeway. FSD will stop for lights/stop signs, but that's about it. FSD Beta is what Tesla is typically known for and what many YouTube videos are showing. FSD Beta will stop at red lights and merge into freeways. Most people use FSD interchangeably, but they are not the same thing.
