If the dash cam has a parking monitoring function, it can still record after the vehicle is turned off. Below are the functions of a dash cam: 1. Record driving footage: It records information such as mileage and speed. Models with a GPS module can also track the vehicle's location and route. Analyzing the collected vehicle and driver operation data helps optimize vehicle performance and correct poor driving habits. 2. Alarm function: According to national standards, continuous driving should not exceed 4 hours, and driving time within 24 hours should not exceed 8 hours; otherwise, it will be considered fatigue driving. 3. Assist in determining traffic accident liability: It records the vehicle's driving status (speed, braking information, turn signals, doors, mileage, location, direction, etc.). By extracting the stored data from the dash cam, it can assist in scientifically determining liability in traffic accidents.

Whether a dash cam can continue recording after the vehicle is turned off depends on the specific situation. The most common issue is the power supply: if it's plugged into the cigarette lighter, the dash cam will stop working immediately after the car is turned off because the cigarette lighter loses power. However, if the vehicle supports delayed power supply or the dash cam has a built-in small battery or capacitor, it can continue recording for a short while. I've personally experienced this—once while waiting in a parked car, the dash cam recorded a passing motorcycle scraping the car after the engine was turned off, thanks to its built-in battery lasting about ten minutes. Nowadays, many new dash cams also feature a parking monitoring mode, which can automatically activate after the engine is turned off via motion sensors, but prolonged use of this function can easily drain the car battery. Therefore, the best advice is to check the dash cam's manual, configure the power mode properly, and avoid unexpected battery drain troubles.

What is the purchase tax for a 3.0L displacement vehicle?

The purchase tax for vehicles with a displacement above 3.0L is calculated by multiplying the taxable price of the vehicle by the tax rate (10%). In the People's Republic of China, any entity or individual purchasing automobiles, trams, automobile trailers, or motorcycles with a displacement exceeding 150 milliliters (hereinafter collectively referred to as taxable vehicles) is considered a taxpayer of the vehicle purchase tax and must pay the tax in accordance with the provisions of this law. Below are the relevant regulations: 1. Calculation basis: Generally, the vehicle purchase tax is based on the purchase price shown in valid documents such as the 'Unified Invoice for Motor Vehicle Sales' or 'Customs Duty Special Payment Certificate,' and the taxable price for the vehicle purchase tax should be calculated after deducting the value-added tax. 2. The general calculation formula is: Vehicle Purchase Tax = Purchase Price / (1 + 17%) × Purchase Tax Rate.

Why Are There Few Used Volvos in the Market?

Volvo has a high resale value and excellent quality. The reasons are as follows: The main reasons why Volvos are rarely seen in the used car market can be summarized as follows: Volvo's own quality is excellent; Volvo's resale value is quite good; Volvo owners are very loyal. Volvo's Resale Value: Volvo's resale value is very good. Volvo owners tend to praise the car highly. Once they choose a Volvo, they are unlikely to switch to other models, making them loyal owners. As a result, Volvos are rarely seen in the used car market, and even if they appear, they are quickly purchased by other buyers. Volvo is a luxury brand. Due to its late entry into the Chinese market and its high price, its sales have never been very strong, leading to low market penetration and low resale value. The low resale value discourages many people from buying new Volvos, creating a vicious cycle that results in few Volvos in the used car market. Excellent Quality: Volvo is widely recognized for its safety. Just look at its logo—it features a seatbelt connection. Many people choose Volvo primarily for its safety and reliability. Additionally, Volvos can be driven for a long time without frequent issues. Target Audience: People who choose Volvo models typically prioritize safety and are often very loyal. Unless the car develops quality issues requiring replacement, they will keep their Volvos for a long time. As long as the quality remains intact, they will drive the car until it is scrapped.

What Causes the Unstable Idling Speed of Wuling Hongguang?

There are many reasons for the unstable idling speed of Wuling Hongguang. Excessive Carbon Deposits: Dirt from the air and sludge from gasoline can easily cause the vehicle's throttle to become dirty, leading to poor operation of the idle speed control valve. Excessive carbon deposits can result in incomplete valve sealing, poor fuel injector atomization, and insufficient combustion. Other Reasons: Exhaust pipe blockage, leading to poor exhaust flow, or air leakage causing insufficient vacuum. Aging wiring or issues with the ECU—these phenomena are unlikely to occur in the short term, so it is recommended that owners avoid installing additional devices on the vehicle. Insufficient cylinder pressure or natural wear—these phenomena also do not occur in the short term.

What does motorcycle electronic quick shifter mean?

Motorcycle electronic quick shifter, officially known as a gear shift assist system, was originally a racing technology that significantly enhances a rider's shifting speed during competitions while maintaining engine RPM. It is an electronic device, similar to other electronic assistive devices applied on motorcycles, and also consists of three parts: sensors, a computer module, and an actuator. Below is an introduction to the quick shifter system: 1. The quick shifter system is composed of three parts: sensors, the main unit, and wiring harness. Sensors are generally installed at a certain position on the gear lever, while the main unit can be mounted anywhere on the bike. Different motorcycle models may have different wiring harnesses. 2.
