No. There are many cars that have autonomous driving features, including adaptive cruise control, lane detection and collision warnings. 'Full self-driving' (FSD) is being tested on many EVs but most notably by Tesla (in the USA). The technologies being used include multiple sensors, cameras and GPS to create a live view of road conditions, traffic and hazards. The car handles all decisions and operates everything, including steering inputs.
