Tesla does not offer a "driver-free" car. While Tesla vehicles are equipped with advanced driver-assistance systems, such as Autopilot, they still require a driver to be present and attentive behind the wheel. Autopilot is designed to assist with certain driving tasks, such as steering and braking, but it is not a fully autonomous system. Tesla has been working on developing self-driving technology, known as "Tesla Full Self-Driving," but as of my knowledge cutoff in September 2021, it is still in a beta testing phase and requires driver supervision. It's important to remember that even with advanced driver-assistance systems, drivers are responsible for operating their vehicles safely and following all applicable traffic laws.
