The share of newly registered passenger cars worldwide produced without provisions for assisted driving systems has become smaller and smaller in recent years. According to the Statista Mobility Market Insights, “regular” cars made up a minority of only 7 percent of newly registered cars around the globe in 2023. The transition to autonomous-ready cars has been a quick one: In 2014, cars without assistance systems were still in the majority at 55 percent of all newly registered ones and that number stood at around a quarter in 2018.
There are six different automation levels for passenger cars in the classification SAE J3016 by standards developer SAE International, four of which are included in the chart. Autonomous driving ability is displayed as levels 0 to 5. In levels 1 and 2, the autonomous driving functions assist the drivers (so-called assisted mode). Automated driving provisions of of level 3 are now entering regular production, while level 4 is expected by 2025.
Level 3 is the lowest level of this automated mode. Vehicles whose systems meet level 3 requirements can drive independently to some degree, with the driver taking over the wheel again upon request and with advance notice. From level 4, vehicles can drive independently without the driver having to take over. In levels 1 and 2, the driver can be assisted by the autonomous driving systems, yet he or she can not turn attention away from the road. In level 1, either braking or steering can be assisted. In level 2, a combination of both is possible, equipping the car lane centering and adaptive cruise control capabilities.
