I won't dispute that the branding is hyperbolic (isn't all/most branding?).
Do you think Tesla's support page describing Autopilot and Autopilot with Full Self Driving is clear enough? https://www.tesla.com/support/autopilot
For instance, there's this paragraph: "Autopilot and Full Self-Driving Capability are intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any moment. While these features are designed to become more capable over time, the currently enabled features do not make the vehicle autonomous."
