Why can't domestic cars use pop-up headlights?

[DelMorgan]

Reasons why pop-up headlights are banned in domestic cars: 1. To protect pedestrian safety, as pop-up headlights often cause parts to scatter upon impact, posing risks to pedestrians; 2. Pedestrians who are knocked down may hit the pop-up headlights again, causing secondary injuries; 3. The design structure of pop-up headlights does not conform to aerodynamics, increasing wind resistance; 4. Prolonged use of pop-up headlights can lead to jamming, causing uneven opening on both sides, which may pose dangers during driving. Pop-up headlights refer to a hidden headlight design that retracts into the vehicle's front hood when turned off and flips up when turned on.
