Is It Safe to Stay in a Car During a Thunderstorm?

It is safe to stay in a car during a thunderstorm because the car's body is primarily made of metal. When the doors and windows are closed, the car forms an enclosed space similar to the principle of a "Faraday cage." Reasons why it is safe to stay in a car during a thunderstorm: Lightning protection involves connecting metal objects with wires or other conductive materials. When high-voltage lightning occurs, the potential of these metal objects becomes nearly equal, preventing a potential difference and thus no current flow. Precautions for driving during a thunderstorm: Reduce driving speed. Although staying inside the car is relatively safe even if the car is struck by lightning, there is no guarantee that all car components will remain intact, especially the tires. While tires are not made of metal, they can conduct electricity when wet from rain. In the event of an extremely strong thunderstorm, there is a risk of tire blowouts. Avoid using mobile phones during thunderstorms. It is advisable to minimize mobile phone usage as the signal's magnetic field can change during a thunderstorm, and the powerful discharge of lightning can generate a strong electromagnetic field in the surrounding area.

Does Water in the Exhaust Pipe Affect the Engine?

If only a small amount of water enters the exhaust pipe, it will not have a significant impact on the engine. However, if too much water enters, it can affect the engine's operation, leading to stalling while driving. According to the principles of air pressure, the likelihood of water entering the engine through the exhaust pipe is very small. Additionally, the exhaust pipe is designed with waterproofing in mind. During design, the exhaust pipe has a certain degree of inclination rather than being completely straight, which effectively prevents water from entering and provides good waterproofing. If a large amount of water flows into the exhaust pipe and cannot be quickly drained, it may cause water accumulation in the muffler. Excessive water accumulation can lead to poor exhaust flow, which in turn affects the engine, resulting in phenomena such as insufficient power. Apart from reduced power, the engine may also frequently experience increased noise, higher fuel consumption, and stalling. When driving through water, it is advisable to slow down or stop to observe. If the water level reaches two-thirds of the bumper or tire height, continuing to drive through the water poses certain risks. If the water level is observed to be high, it is best to detour and avoid forcing passage. During driving, maintain a low gear and steady speed, and avoid stopping midway, shifting gears, or making sharp turns of the steering wheel.

What are the precautions for driving on the highway at night?

Precautions for driving on the highway at night include: the use of turn signals, the use of high beams, keeping a distance from large trucks, etc. Here are the relevant details: 1. Turn signals: Visibility is poor at night, and the following vehicle often cannot anticipate the driving behavior of the vehicle ahead. If the vehicle ahead suddenly changes lanes when the distance is very close, the following vehicle may not have enough time to brake, leading to a rear-end collision. 2. High beams: Never use high beams when overtaking, as the vehicle ahead will see only a blinding white light in the rearview mirror, making it difficult to judge the distance from the following vehicle, which can easily lead to dangerous situations during overtaking. 3. Keeping a distance from large trucks: There are quite a few large trucks on the highway at night. Some drivers change lanes without considering the smaller vehicles behind them, so it is essential to use your lights to alert them when overtaking a large truck. At night, never drive behind a large truck.

How long after deducting 12 points can I apply for a D license upgrade?

Once 12 points are deducted in a scoring year, you must wait for one year before you can apply for a D license upgrade. This is because you need to have no record of a full 12-point deduction in the most recent scoring cycle. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses": If you already hold a motor vehicle driving license and apply to add an additional permitted vehicle type, you must have no record of a full 12-point deduction in the current scoring cycle and the most recent scoring cycle before application. A D driving license is a type of driving license (driver's license) that permits the operation of ordinary three-wheeled motorcycles and the vehicle types permitted by E and F licenses. Taking the upgrade from a C1 license to a D license as an example, the process is as follows: Bring your ID card, driving license, medical examination certificate, and a one-inch white-background photo to the local vehicle management office to submit the upgrade application. Then, enroll in a motor vehicle driver training school and complete a 10-day course on traffic regulations and related knowledge. With the study certificate for traffic regulations and related knowledge and your ID card, take the subject one exam at the vehicle management office. After passing subject one, you can voluntarily choose a training school for subjects two and three. After completing the training period, the training school will schedule the exams with the vehicle management office. Upon passing the exams, your old license will be collected, and a new license will be issued.

What Are the Causes of Abnormal Brake Noise in Cars?

Car brake abnormal noise is caused by: using inferior or overly hard brake pads, and the presence of sand or foreign objects between the brake pads and brake discs. Using inferior or overly hard brake pads: When the brake pads rub against the brake discs, they produce a squeaking noise. Therefore, it is essential to use high-quality brake pads when replacing them. The abnormal noise will gradually disappear as the brake pads and discs wear in, and the braking force will also improve, requiring no special treatment. However, hard braking should be avoided as much as possible, as it can accelerate the wear of the brake pads and discs, affecting their long-term service life. Presence of sand or foreign objects between the brake pads and brake discs: During normal driving, it is inevitable to encounter some complex road conditions. Due to the unique design of disc brakes, some sand or foreign objects may get between the brake pads and discs, causing abnormal noise when braking. You can try slamming on the brakes a few times to help expel the particles. Brake pad installation issues: After installing the brake pads, the calipers need to be properly adjusted. Issues such as the brake pads being too tightly fitted to the calipers or being installed backward can cause abnormal brake noise. Try reinstalling the brake pads or applying grease or specialized lubricant to the connection between the brake pads and calipers to resolve the issue.

What brand is the Buick Excelle transmission?

The manufacturer of the Buick Excelle transmission is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the world's highest market share. The Buick Excelle transmission uses either a CVT continuously variable transmission or a 5-speed manual transmission. The continuously variable transmission does not have specific gears. In operation, it is similar to an automatic transmission, but the change in speed ratio differs from the gear-shifting process of an automatic transmission—it is continuous, thus providing sustained and smooth power transmission. For the Buick Excelle's transmission in daily use, the following points should be noted: Do not go too long without changing the transmission oil. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing; Avoid prolonged coasting in neutral. When driving a manual transmission model, many 'experienced drivers' tend to coast in neutral, but for automatic transmission models, coasting in neutral can cause the automatic transmission to overheat, and shifting back into D gear can create a certain impact; Never shift into D/R gear before the vehicle has come to a complete stop. Many drivers, to demonstrate their 'smooth' operation, shift directly into reverse gear before the vehicle has fully stopped, which can cause significant damage to the transmission gears and, over time, lead to gear grinding and other faults; Do not frequently climb steep slopes in D gear. When facing steep slopes, automatic transmission vehicles often overheat due to high load or shift up too early, resulting in insufficient climbing power. In such cases, manual mode can be used to limit low gears or sport mode to protect the transmission; Do not tow over long distances. When an automatic transmission vehicle breaks down, a flatbed tow truck should be used to move the vehicle onto the tow platform while it is in N gear. Towing ropes or direct towing by another vehicle should not be used.
