What are the hazards of installing streamers on the front of a car?

The hazard of installing streamers on the front of a car is that it may cause traffic police to mistake the vehicle for a suspicious one and intercept it. The following is an introduction to car decoration: 1. Meaning: Car decoration refers to improving the aesthetics of the car's exterior and interior by adding some accessories, which are called decorative items. 2. Interior: Car interior decoration involves altering the appearance of the car's inner roof, floor, console, and other surfaces by installing, replacing fabrics, or placing ornaments. 3. Exterior: Car exterior decoration involves adding or modifying external parts such as front and rear bumpers, body kits, and spoilers without changing the car's original functions and structure.

How many points are deducted for stalling during the hill start in Subject 2?

During the hill start in the fixed-point parking exercise, stalling once deducts 10 points. Other point deduction items are as follows: After parking, if the right side of the vehicle body is more than 30 cm away from the roadside line, 10 points are deducted; if more than 50 cm, 100 points are deducted; crossing or touching the line results in a 100-point deduction. After parking, if the front bumper is not aligned with the pole line and the deviation is within 50 cm, 10 points are deducted; if the deviation exceeds 50 cm, 100 points are deducted. After parking, if the parking brake is not fully engaged, 10 points are deducted. Failing to complete the start within 30 seconds results in a 100-point deduction. Starting the engine without the gear in neutral or park results in a 100-point deduction. During the start, if the vehicle rolls back less than 30 cm, 10 points are deducted; if it rolls back more than 30 cm, 100 points are deducted. Key points for the hill fixed-point parking operation: Upon hearing the instruction for "hill fixed-point parking" (approximately 20 meters from the pole), turn on the right turn signal, steer appropriately to the right, and slowly drive the vehicle straight along the right side of the road, paying attention to the distance between the vehicle body and the right roadside line. When the vehicle is about 10 meters away from the parking pole, slowly, accurately, and steadily approach the target position. Aim accurately at the target, using a specific point on the parking pole and the windshield (or hood) (this point should be determined during practice due to differences in vehicle models and driver height). When the specific point on the windshield aligns with the parking pole, meaning the vehicle’s bumper is aligned with the parking pole line, stop immediately.

What are the reasons why an automatic transmission car cannot start or ignite?

Possible issues include the steering wheel, parking gear, smart key, battery, etc. Below is an introduction related to automatic transmissions: 1. Automatic Principle: The engine's power is transmitted through the gearbox, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, more gears mean better fuel efficiency. 2. Driving Techniques: For manual transmission cars, it is advisable to shift gears at higher RPMs. Engines are designed to operate at higher RPMs, and parameters such as dynamic balance and rotational inertia of various components are also designed with high RPMs in mind. If the engine operates for extended periods under abnormal conditions, the load and wear on internal components naturally increase, leading to frequent shaking and knocking, which can affect the engine's lifespan. Choosing 3000 RPM as the shifting point ensures that after shifting, the engine operates at around 2300 RPM, keeping it within a healthy RPM range.

Can the air conditioning be left on while the car is running?

It is possible to keep the air conditioning on while the car is running, but it is not recommended to do so frequently. On one hand, it leads to higher fuel consumption, and on the other hand, idling can cause the engine to accumulate carbon deposits more easily, which may degrade engine performance over time. Tips for using air conditioning: After the car has been exposed to the sun for a long time, you should first open all four doors and the sunroof to allow air to circulate inside the car for about 3 minutes. This will quickly lower the interior temperature, making the air conditioning more effective when turned on. Using the recirculation mode blocks hot outside air, creating a sealed space inside the car, allowing the air to circulate rapidly under the effect of the air conditioning for faster cooling. Once the interior temperature has dropped, it is recommended to switch to the fresh air mode every 30 minutes to purify the air inside the car, then switch back to recirculation mode after 5 minutes. Turn off the air conditioning about 5 minutes before parking to protect the engine and save fuel. Hazards of prolonged idling: When the car is idling, incomplete combustion of gasoline produces a significant amount of carbon monoxide. The longer the idling time, the higher the concentration of carbon monoxide around the vehicle. Prolonged idling can result in extremely high carbon monoxide levels inside the car, which can lead to carbon monoxide poisoning or even death if passengers are present, potentially causing safety accidents. Therefore, it is important not to keep the windows completely closed. Instead, open them slightly to maintain air circulation between the inside and outside of the car.
