Why Aren't Cars Waterproof?

[LaJanelle]

Cars are not waterproof for the following reasons: 1. Impracticality: While it is technically possible to design waterproof car models, it is impractical due to high costs and the fact that waterproofing would also prevent air from entering the vehicle. 2. Interior design: Cars have numerous gaps and electronic components, making effective waterproofing difficult. Precautions for car waterproofing include: 1. Driving in rain: Pay close attention to the depth of water on the road. When encountering deep water areas, maintain a low gear, steady throttle, and pass through slowly. 2. During car washing: Avoid directing high-pressure water jets straight at sealing rings, as this can deform them under pressure, allowing water to enter the vehicle and significantly damaging the seals. 3. Cleaning seals: Sunroofs use rubber sealing rings for waterproofing, so it's important to protect these seals from dust during use.
