There is a lot of company working on self-driving car technology, such Waymo, Baidu, Tesla, etc. If this technology can be matured, it will be one of the most impactful technology development in this decade. Before we are talking about how mature this technology, we need to about the standard of self-driving car technology. Although there are different standards, most of them have divided this technology into 6 levels. L0 fully controlled by a human driver. L1 is mainly controlled by a human driver but assisted but the system at one aspect, like ABS. L2 is mainly controlled by a human driver but assisted but the system at multiple aspects like ABE. L3 mainly is controlled by the system, Human driver has to monitor the situation and take over when needed. L4 is fully controlled by the system, but only available for some conditions or some area. L5 is fully controlled by the system. Most of the car has already reaching L1 or L2. Tesla is at L3, and Waymo is at L4. Still, no L5 self-driving cars are created. If Level 5 is reached, it will release manpower of the millions of drivers in the world. People are looking forward to this come true, but the process is not as quick as we thought. It has been staying at L4 for years and there are few available areas. This may take 10 years to reach L5 or at least L4 worldwide available.
