This paper presents the basics of autonomous vehicle as well as technologies that enable a vehicle to be self-driving. Taking into the consideration the fact the major causes of traffic accidents are by human errors, with the application of intelligent vehicle systems would be a great help to go to the "zero vision" of life losses in traffic accidents. According to traffic accident statistics, 75% or more of fatal accidents have been caused by human factors such as: lack of attention, stress, loss of orientation, fatigue, health condition, etc. In 24% of cases unexpected behaviors causes traffic accidents and only 0.7% of them are due to technological failures. For this reason, the potential of driver assistance and active safety systems that support the driver in complicated traffic situations is much higher when compared to passive safety. From this perspective it can be seen that with the construction of a self-driving vehicle, 75% of cases of fatality are likely to have a significant decrease in the percentage of life-loss in total number of traffic accidents. On the other side technological errors that affect the occurrence of fatal accidents may have a slight increase but all this based on the prejudice that in future there will be more vehicles with intelligent systems failures that may occur in disfunctional system.
