What are optional features in cars?

[McBrianna]

Optional features refer to configurations that are not part of the standard equipment for a particular car model. Standard features are mandatory, while optional features can be selected according to the buyer's preferences or needs when placing an order. Below is an introduction to related content: 1. More expensive configurations are not necessarily better: The more accessories a car has, the higher its maintenance risk rate. Appropriate decorative configurations can achieve both safety and comfort. Thus, "safety" and "comfort" become the two major principles consumers should follow when selecting configurations. 2. Optional features: Optional features often belong to enrichment configurations, which do not affect the vehicle's safety performance or power performance but can enhance comfort, practicality, and high-tech experiences, such as parking sensors and digital head-up displays. 3. Identification: Optional features are usually marked in the car's parameter specifications, such as "hollow circles" and "thin solid lines," though the symbols used may vary among different car manufacturers.
