What's the difference between optional and standard?

The difference between optional and standard is as follows: 1. Different meanings: the standard of automobile refers to some standard configurations of automobile manufacturers, such as the level of airbag brake anti-lock system, which is already a national mandatory standard configuration based on national safety standards or own standards when leaving the factory. Matching is to choose the configuration within the scope according to your own needs. 2. Different ranges: optional configurations are often rich, which will not affect the safety performance of the whole vehicle, but the dynamic performance will improve the comfort, practicality and high-tech experience, such as reversing radar, digital head-up display and other configurations. The standard car looks ordinary, without any decoration. Other types include skylights, chrome-plated doors and fog lights.
