Cars are becoming increasingly automated. Drivers already benefit from a wide range of advanced driver-assistance systems (ADAS), such as lane keeping, adaptive cruise control, collision warning, and blind spot warning, which are gradually becoming standard features on most vehicles. Today's automated systems are taking over an increasing amount of responsibility for the driving task. It is expected that soon, sensors will take the place of human impulse, and artificial intelligence will substitute for human intelligence. This process is defined through various level steps, from low levels of automation where the driver retains overall control of the vehicle in level 1, to a fully-autonomous system in level 5.
