When driving at high speeds, opening the sunroof can significantly increase wind resistance, leading to higher fuel consumption and potential safety hazards. The noise generated can also irritate the driver's eardrums, affecting driving safety. Below is a detailed analysis of the specific reasons for sunroof leakage: 1. Clogged sunroof drainage outlets: Blocked drainage outlets hinder the flow of rainwater, causing it to gradually seep into the car. This issue often arises when owners neglect regular cleaning of the roof, allowing debris to wash into the drainage outlets with rainwater. To address this, a wire hook can be used to remove the debris from the drainage holes, or a repair shop can use an air gun to blow out the obstructions. 2. Damaged sunroof seal: The sunroof seal, made of rubber, can deteriorate over time and become damaged due to repeated friction with the sunroof glass, leading to poor sealing and leakage during rain. Regular inspection of the seal's condition is essential, and damaged seals should be replaced promptly with high-quality, corrosion-resistant options. 3. Roof deformation: If the car is involved in a collision, the body may deform. Improper restoration during repairs can result in inadequate sealing and subsequent leakage. It is crucial to adhere strictly to the original vehicle standards during accident repairs to prevent misalignment of parts and potential leakage risks.

Having driven for decades, I can say that opening the sunroof at high speeds poses significant risks. The wind noise roars like a train, making your ears ring and even drowning out navigation prompts, which can distract you and lead to accidents. The car sways, especially in crosswinds, causing the steering wheel to feel loose and compromising control. Rain or dust can also blow into the cabin, dirtying the interior. Worse yet, the sunroof's tracks and seals wear out faster under high-speed airflow, leading to costly repairs down the line. My advice is to avoid opening the sunroof when driving over 80 km/h—using the AC for ventilation is safer and more reliable. I've seen many new drivers make this mistake, resulting in unnecessary trouble. Safety first—developing good habits saves both peace of mind and money.

As a young person who loves to experiment, I enjoy driving with the sunroof open to feel the breeze, but never try it on the highway. The wind noise is as loud as an airplane taking off, drowning out the music, and you have to shout to talk to friends—how awkward! Your hair whips around and hits your face, making it hard to even keep your eyes open, leaving you feeling uncomfortable. What’s worse, the increased wind resistance noticeably raises your car’s fuel consumption, making it uneconomical with the extra gas money spent. Trying to stay cool in summer turns into torture—air conditioning is the real solution. Driving with the sunroof open at low speeds is enjoyable, but on the highway? Not worth it—more trouble than it’s worth.

When tinkering with car parts, I've noticed that opening the sunroof at high speeds is a mechanical killer. The sunroof's tracks and sealing components wear out faster under the impact of high-speed airflow, leading to leaks or jamming when opening/closing. Over time, repair costs add up. Excessive wind force can also loosen the sunroof frame, creating safety hazards. The noise issue further degrades the driving experience. In contrast, opening windows at low speeds protects the equipment. It saves money and hassle, so it's best to keep the sunroof tightly closed at high speeds.
