The prototype smartphone app allows the user to start the car and control brakes, steering and throttle while also imparting control of gearshifts. In this remote pilot mode, the car will reach a maximum speed of 6km/hr. The car will stop if the smartphone or the car key get more than 33ft away from the vehicle itself. We are not sure about if the car’s collision avoidance sensors would kick in or not when in this mode.
Another prototype that has been revealed will be able to carry out 180-degree multi-point turn if the user is in a narrow street where making a proper U-turn isn't possible. The car makes use of its ultrasonic sensors for searching hazards in the environment and then autonomously performs an about-turn in as many steps as required. Check out this video for more details:
