During driving, the driver may be attracted by the kitten ornaments, making it difficult for the driver to maintain concentration and making it easy for accidents.
If the kitten ornaments are not firmly fixed and fall apart during sudden braking, they may easily fall into the car, causing damage to the front windshield or injuring people inside the car. Moreover, it is easy to slip to the brake pedal, affecting braking and posing a safety hazard.
