Is it necessary to remove a business card that has fallen into the car window?

[StEvangeline]

It is not necessary to remove it as long as it does not cause any malfunctions. Here is some relevant information: 1. Noise generation: The business card may rub against the car door and produce noise, but for the vehicle, the noise generated by the card is almost negligible. 2. Jamming the window lifting mechanism: This issue is also unlikely to occur because business cards are relatively thin and usually fall directly to the bottom of the door panel, thus having minimal impact on the window lifting mechanism. 3. Inspection: Before driving, if you notice a small card on the window, be sure to remove it first. If you are not careful, the card may be pulled into the car door when the window is rolled down.
