Why is it easy for water to wash away license plates?

[OKira]

There are several main reasons why water can easily wash away license plates: 1. Many car license plates are fixed with only two screws during installation, usually securing the upper part of the plate, while the lower part is mostly left unsupported. This method of fixation is not very secure. When the car drives through deep water, the resistance of the water can wash the plate away, especially the front license plate. 2. The reason license plates are prone to falling off is also related to the bumper. Although the bumper can act as a buffer during a collision, it is prone to deformation under external force. When driving, strong water flow can pull the screws out of the deformed bumper, causing the front license plate to fall off.
