The goal of this post is to describe the levels of autonomous driving technology or so called Automatic driving technology classification we have today in brief. 

The car was invented more than 100 years ago, in these 100 years, the car technology has been progressing. Our cars, for example, are now computer-controlled with EFI technology. But in the old days, carburetors were used, and carburetors could mechanically allow fuel and air to enter the cylinders in different ways to make the car run more smoothly. Another example been, we used to use manual cars, but now we basically drive automatic cars, which are an advancement in automobile technology.

	Speaking of the Automatic Driving Classification. Basically, autonomous driving can be divided into several levels from L0 to L5(level 0 to level 5). For example, the L0 level, this cannot be called automatic driving, this is called artificial driving. This artificial driving is the car is completely a human tool, completely cannot replace any human driving function. This is about from the invention of the car until 1990, and before 1990 basically the car is not any assistance function.
	Since 1990 there has been a certain amount of car-assisted human functions, which we call L1 autonomous driving or assisted driving. Assisted driving now many cars have such as fixed speed cruise control, (in simple terms is to set a speed to the car and then the car will always go forward at this speed), and ABS system is also called anti-lock system, that is, when the car brakes hard the car is not dead but always in our control and not to skid. ESP system, which allows the braking force to be distributed among the four wheels, then prevents the car from skidding or rolling over. These systems all assist human driving to some extent, and we call it L1 level autonomous driving.
	L2 level autonomous driving, we can call it partially autonomous driving. Since 2010, L2 autonomous driving has been standard. Partial autopilot means that it can automatically accelerate, decelerate, and control the direction of the car under certain circumstances.
	L3 level autonomous driving is called conditional autonomous driving. It is possible to achieve autonomous driving under certain conditions. As we said, L2 driving can control acceleration, deceleration, and direction, but it cannot change lanes. However, L3 driving can change lanes on top of L2 driving. Partial driving requires the driver to always monitor the road environment, while conditional autonomous driving does not always require monitoring, but simply intervenes under certain circumstances. L3 autonomous driving is not yet complete, and it is hoped that a mature L3 level of autonomous driving can be achieved by 2030.
	There are two other types of autonomous driving, L4 and L5.For example, if a person wants to go from home to school, they only need to set a location on the GPS to go from home to school, and the car can automatically take me from home to school, and I don't have to worry about anything on the way.
	L5 level autonomous driving is also called fully autonomous driving. The car will not even have a steering wheel. Both L4 and L5 will take about 20 to 30 years to really happen. But if this is really achieved will be the maximum liberation of human beings at the same time can also greatly improve safety. If a traffic accident occurs under L4 and L5 autonomous driving, the responsibility lies not with the individual but with the car company.
