All cars produced by Tesla after Oct. 20 will be equipped with “full self-driving” hardware, the automaker announced yesterday.

Tesla’s semi-autonomous Autopilot software has been deployed in current cars, but is technically still being tested on the road. Doubts were cast on its effectiveness after one motorist’s death in May. The hardware announced yesterday takes the cars’ autonomy even further, allowing cars to navigate suburban streets and find a parking space.

When Autopilot was first released, the company was careful to note that it was not a truly hands-off system; the driver needed to take the wheel more often. The new self-driving hardware – including eight cameras and 12 ultrasonic sensors – gives the car better “vision” and improves its performance in inclement weather or low light. At 250 meters of range, it can also detect objects at twice the distance of the software system.

The hardware will be available on new Model S, Model X, and the upcoming Model 3. Like Autopilot, it will learn from its drivers. Tesla’s blog said “we will further calibrate the system using millions of miles of real-world driving” before the hardware reaches its full capability.

Tesla CEO Elon Musk discussed the feasibility of installing the new hardware in older vehicles on Twitter on Wednesday, saying that retrofitting an older car would cost more than buying a new one. With the Model S starting at $66,000, that’s nothing to scoff at.
