Owners of Tesla’s Model S sedan in North America experienced a radical software upgrade to their vehicle as the company “pushed” out a suite of semi-autonomous technology that allows the vehicle perform some of the driving duties once exclusively done by human drivers. The software technology works in synergy with ultrasonic sensors, cameras and radars to bring the driverless car promise of tomorrow to the present day.

It must be noted that this is a tentative test of the driverless car reality in actual practice, and the company advises drivers to exercise caution while implementing this feature, stressing that any accidents that occur while using the autopilot remains the responsibility of the driver.

The key features of the autopilot include auto park, auto steer, and auto lane change. Google previously publicized its fully autonomous vehicle project, while all other major car makers are in this race towards producing the first fully autonomous vehicle.  For instance, Audi has been working on its Pilot Assist product, even though it is yet to implement this into any of its vehicles, yet.

Only cars built from late September of last year onward – about 60,000 of the 90,000 Model Ss on the road to date – have the requisite sensors pre-installed to enable Autopilot, which costs $2,500 to activate.
