Self Driving Cars are on Road

With version 7.0 of Tesla software, Model S can drive in autopilot mode, hands free. At low speeds the car can answer you summoning and can park itself in the garage as well. 2014 Mercedes S class has active lane assist capability too, but it wont turn on unless your hands are on the steering. This is where Tesla scores. As awesome as it sounds, you are still required to be paying attention during autopilot. If the sensors or any other component malfunctions, responsibility of resulting accident will still be of the person who is supposed to be driving, that is, the car drives but still, you are the driver.

The Tesla Motors Team posts- 'A forward radar, a forward-looking camera, 12 long-range ultrasonic sensors positioned to sense 16 feet around the car in every direction at all speeds, and a high-precision digitally-controlled electric assist braking system. Today's Tesla Version 7.0 software release allows those tools to deliver a range of new active safety and convenience features, designed to work in conjunction with the automated driving capabilities already offered in Model S. This combined suite of features represents the only fully integrated autopilot system involving four different feedback modules: camera, radar, ultrasonic, and GPS. These mutually reinforcing systems offer real time data feedback from the Tesla fleet, ensuring that the system is continually learning and improving upon itself. Autopilot allows Model S to steer within a lane, change lanes with the simple tap of a turn signal, and manage speed by using active, traffic-aware cruise control. Digital control of motors, brakes, and steering helps avoid collisions from the front and sides, as well as preventing the car from wandering off the road. Your car can also scan for a parking space, alert you when one is available, and parallel park on command.'
