Right. Wikipedia defines it as such

A self-driving car, also known as a autonomous car (AC), driverless car, robotaxi, robotic car or robo-car,[1][2][3] is a car that is capable of operating with reduced or no human input.

But also

Organizations such as SAE have proposed terminology standards. However, most terms have no standard definition and are employed variously by vendors and others. Proposals to adopt aviation automation terminology for cars have not prevailed.

So there’s no one definition. It is driving by itself. You don’t have to do any driving. But you should keep alert so if something happens you can taker over. Seems like it fits with the general use imo but doesn’t fulfill the more stringent definitions.
