Tesla Motors claims that its cars have full self-drive capability in almost all circumstances, claiming that their autopilot is at least twice as safe than an human driver. The system is capable of driving the vehicle for long or short distances, without the need of any action from the driver. The only thing that should be done is to tell the car where you want to go; If nothing is said, the car will scan the calendar and take you to the already scheduled destination, or take you to your own home (if the calendar is empty).
The Tesla electric car will decide which are the ideal routes, navigate through urban routes, manage complex intersections with traffic lights, stop signs and roundabouts, as well as dealing with freeways that are very busy with cars moving at high speed. When arriving at the desired location, you only need to get out of the car and it will go into the parking mode, automatically searching for a place where it can park itself. Then, to summon it back, you only need one tap on your phone.
Everything that was said is possible thanks to the eight surround cameras installed in their cars; these provide a 360-degree visibility around the car within a distance up to 820 ft. This view is complemented by twelve ultrasonic sensors, which allows the detection of several objects at a much greater distance, and by a radar (forward facing) with advanced processing, providing additional date on the world, at a wavelength capable to see through heavy rains, fog, dust and even the car ahead. This data is processed by an onboard computer which provides a worldview that a driver alone can not access, seeing in all directions simultaneously.
