Is there any impact if accidentally driving over a speed bump at over 100 km/h?

Accidentally driving over a speed bump at over 100 km/h once in a while has little impact, but you should pay attention to slowing down next time. The methods for passing over speed bumps are introduced as follows: Reduce speed in advance: When encountering a speed bump while driving, it is best to slow down in advance and then pass over the speed bump straight on, balancing the impact force on both tires and ensuring the suspension system on both sides bears the force evenly. Do not slam on the brakes or step on the accelerator, allowing the vehicle to pass over the speed bump habitually. This approach is both safe and protects the vehicle's suspension and steering systems, causing minimal damage to the car. Passing over the speed bump with one side: When passing straight over a speed bump, the car's bumps and jumps will be more significant. However, when passing over the speed bump at an angle or with one wheel, the car's jumps are less pronounced, and the number of sways is also reduced when passing with a single wheel.

Are new cars equipped with safety hammers?

Some new cars come equipped with safety hammers. It is best to install the car safety hammer on the central frame of the car where it is conspicuous and easily accessible. Correct usage of a safety hammer: Take out the safety hammer from the car and directly strike the four corners of the tempered glass. When a small crack appears, it indicates that the internal stress distribution of the glass has been significantly compromised, leading to the instant formation of numerous spider-web cracks. At this point, a few more strikes will shatter the glass. If the glass has a film, additional force is needed to kick it open, as the film has anti-shatter properties and won't detach without sufficient external force. Car safety hammers, also known as multifunctional safety hammers, are tools installed in vehicles to break car windows for escape during emergencies or disasters. There are numerous brands of car safety hammers, with varying functions and styles. The hammer body can be made of plastic, wood, or steel, while the hammer head is always metal.

What Causes the Sound When Braking in Reverse Gear for Automatic Transmission?

The sound that occurs when pressing the brake pedal while reversing is likely coming from the brake disc and pads. This issue is usually caused by the hardened surface layer of the brake pads. Additionally, it could be due to the chamfering effect that develops after prolonged use of the brake pads. The solution is to have the brake pads resurfaced at a 4S repair shop. Handbrake Operating Principle: The handbrake, technically referred to as an auxiliary brake, operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. The handbrake system also includes a return spring. When the handbrake is engaged, the spring stretches; when released, it returns to its original length. Over time, this spring can also deform with extended use. The Necessity of Proper Brake Usage: The handbrake is a frequently used system. Proper and correct usage ensures smoother operation in the future, extends its adjustment intervals, and reduces maintenance and replacement costs.

Why Does the Windshield Appear to Move Slowly?

The reasons why the windshield appears to move slowly include the influence of angles and distance. The specific explanations are as follows: Influence of Angles: Close one eye. When a long stick aligns with the central line of your vision in front of you, you can only see the end of the stick and have no idea how long it is. When the stick forms a certain angle with your line of sight, you realize it is a stick, but you still cannot accurately perceive its true length—it appears shorter. The smaller the angle, the shorter it seems. Only when the stick is perpendicular to your line of sight can you fully perceive its true length. Influence of Distance: The closer an object is, the greater its angular velocity; the farther it is, the smaller the angular velocity (linear velocity is like the base of an isosceles triangle, distance is the height of the triangle, and the angle between the vertex and the base represents the angular velocity. Clearly, if the base length is the same but the height differs, the size of the vertex angle will vary significantly). For example, when flying in an airplane at high speed, objects on the ground appear to move very slowly because they are too far away, resulting in a very small angular velocity.

Are company-owned vehicles scrapped after 15 years?

Company-owned vehicles are not scrapped after 15 years, but they must undergo regular annual inspections, otherwise they will be forcibly scrapped. The scrapping time for vehicles registered under a company name is the same as that for private cars. Private cars no longer have a scrapping age limit. However, for vehicles converted from commercial to non-commercial use, they must be scrapped after eight years, not 15. Vehicle scrapping standards: Starting from May 1, 2013, China has revised the scrapping regulations for private cars. Private cars are no longer scrapped based on age but are forcibly scrapped when they reach a maximum mileage of 600,000 kilometers. In other words, no matter how many years a private car has been owned, once it reaches 600,000 kilometers, it must be scrapped, even if it has only been driven for five years. Private car inspection standards: According to the latest private car inspection standards in China, small and micro non-operational passenger vehicles can enjoy an exemption from inspection for the first six years, requiring only a biennial visit to the vehicle management office to collect the inspection compliance label. After six years, the vehicle must be inspected annually. After 15 years, the vehicle must be inspected every six months, as long as it has not exceeded 600,000 kilometers. In this case, the vehicle can continue to be driven indefinitely.
