Is it okay to hit an illegally parked car and run away?

It is considered a hit-and-run behavior. While the other party's illegal parking is a violation subject to administrative penalties, you should still compensate for the damage caused to their vehicle according to your liability. Here's how to handle the situation: 1. Take photos as evidence: No matter what vehicle you're using, if you hit someone else's parked car, never flee just because the owner isn't present. At the accident scene, you should immediately take these three photos: one of the scratched area, one of each side of the vehicle body, and one each of the front and rear of the car. These photos can serve as evidence of the damage caused by the scrape and prevent the owner from falsely claiming other damages for extortion. 2. Call the traffic police and insurance company: In case of a scrape, immediately call the traffic police or your insurance company and wait for professionals to arrive to photograph and assess the vehicle damage. This can prevent the owner from inflating the price for private settlement and subsequent extortion attempts, while ensuring reasonable compensation. If you have insurance, this is when your insurance company should step in to handle the relevant claims, so you don't have to worry about paying out of pocket.

How to Remove Cement from Car Surface?

Here are the methods to remove cement from car surface: 1. If less than 12 hours, wet and soak with water. If the cement has been on for less than 12 hours, first wet and soak it with water, then use car shampoo and a towel to wash it slowly, bit by bit. Although this method is slow, the effect is very good. 2. If more than 12 hours, apply acidic solution with a brush. If the cement has been on for more than 12 hours, it will have hardened. You can buy some acidic solution from a pharmacy, dip a brush in it, and apply it to the cement. The cement will be dissolved by the acidic liquid, and then you can rinse it off with water. 3. Pour gasoline on it. Pour gasoline on the cement, wait for it to soften slightly, and then remove the cement by hand (suitable for large-area removal). 4. Use a hair dryer to heat the affected area. Use a hair dryer to heat the part with cement. Due to the different thermal expansion of cement and plastic, the cement will usually fall off automatically. 5. Spray white vinegar. Use a spray bottle to spray white vinegar on the cement, wait for 3-5 minutes, and then gently scrape it off with a hard card. The cement will come off in chunks. Afterward, wash the area where white vinegar was sprayed with car shampoo to ensure no residue remains. 6. If it really cannot be removed, use rubbing compound and a polishing wheel. The cost varies depending on the car.

Is it necessary to install ETC now?

It is necessary to apply for ETC. According to the regulations of the State Council, vehicles without ETC in 2020 will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC cannot be used on highways immediately; the ETC device must be activated before normal use. During free holiday periods, highways can still be used. For users who have already installed ETC, passing through ETC lanes will not incur charges. ETC charging principle: There will be one or more ETC lanes on highways. Through microwave dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the purpose of paying highway tolls without stopping at toll stations is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of queuing and waiting; Green and environmentally friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, minimizing pollution; Cost-saving: Reduces expenses, decreases the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Efficiency improvement: Theoretically, ETC lanes can improve vehicle passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal in the main indicators of the "13th Five-Year" comprehensive transportation development plan that "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.

What is the purpose of the dotted line on the rearview mirror?

The dotted line on the rearview mirror is primarily used to observe situations at a farther distance on the side of the vehicle. Inside the dotted line, the curvature radius is larger, used to observe situations at a closer distance on the side of the vehicle. The combination of these two curvatures helps minimize blind spots in the rearview mirror. The smaller area of the dual-curvature rearview mirror may also feature a small indicator, which functions as a "side blind spot warning system." When there is a potential collision risk on the side of the vehicle, this indicator will flash to alert the driver. If the body of the following vehicle has entered the dangerous area to the left of the dotted line on the rearview mirror, it indicates that the following vehicle is very close to your car, and you should not change lanes at this time. If the left side of the following vehicle's body is close to the boundary between the safe zone and the danger zone, you should be extra cautious, but signaling and changing lanes at this time is still safe. If the following vehicle is in the safe zone, located in the center of the rearview mirror, it means the following vehicle is 15-20 meters away from your car, and you can proceed with normal lane-changing operations. Functions of the dotted-line rearview mirror: A rearview mirror with a dotted line is known as a dual-curvature rearview mirror. Divided by the dotted line, the mirror is mainly split into two parts. The dotted line is located on the outer third of the mirror, with the inner area being the normal reflection zone, also referred to as the standard rearview mirror area. The viewed area here is essentially 1:1, with minimal distortion. The outer area has a greater curvature, providing a wider field of view due to its larger curvature, which helps drivers better adjust their vehicle's position. For example, during reversing, the wider curvature allows for a broader view of the reversing area. The entire dual-curvature rearview mirror acts like a small convex mirror, offering the driver a wider field of vision. Because dual-curvature rearview mirrors are generally smaller in size, they can effectively reduce wind resistance and lower the vehicle's fuel consumption. The warning device on the dual-curvature rearview mirror alerts the driver when there is a potential danger on the side of the moving vehicle, prompting the driver to take evasive action. Most vehicles also come with a rearview mirror heating function. In special weather conditions, activating the heating function can prevent fogging on the rearview mirror, ensuring clear visibility for the driver. During heavy rain, applying a rain repellent to the rearview mirror can help. This repellent forms a thin film on the glass surface, allowing water droplets to slide off quickly. Rain repellent can also be used on the windshield. It's important to avoid scratching the rearview mirror, as the outer shell is plastic and difficult to repaint if scratched. When parking on the roadside, it's advisable to fold the rearview mirrors.

How to Break in a New Car with Tiptronic Transmission?

Here are the methods for breaking in a new car with tiptronic transmission: 1. Warm up the car before starting: After the car has been parked overnight, the engine oil flows back to the oil pan. When the car is started, it takes some time for the oil to fully lubricate all the engine components from the oil pan. If you drive immediately after starting, the internal parts of the engine may not be sufficiently lubricated, leading to abnormal wear. Therefore, it's advisable to warm up the car briefly before driving, waiting until the idle speed stabilizes. 2. Speed control during the break-in period: The speed during the break-in period should be increased gradually. For the first 500 kilometers, try to maintain a speed between 60-70 km/h, with the engine RPM not exceeding 2,200. From 500 to 1,000 kilometers, the speed can be increased to 90-100 km/h, with the RPM generally kept below 2,500. After 1,000 kilometers, the speed can be raised to below 120 km/h, with the RPM not exceeding 3,000. 3. Gear control: During the break-in period, it's important to manage the gears properly with a tiptronic transmission. Avoid suddenly shifting into P or R while driving, as this can cause severe impact to the transmission, potentially damaging it. When shifting into reverse, ensure the car is completely stopped. Additionally, practice using the manual mode on well-paved roads to break it in. 4. Avoid coasting in N gear: While driving, avoid coasting in neutral (N gear). When in N gear, the transmission's power pump stops working, leading to abnormal wear due to lack of coolant and lubrication, which shortens the transmission's lifespan and increases fuel consumption. 5. Avoid emergency braking: Try to avoid emergency braking during the break-in period. Emergency braking can impact the car's braking system. Since the car's components are not fully broken in, frequent emergency braking is detrimental to the break-in process and can also damage the car's chassis. 6. Generally, do not change the oil prematurely: The oil used during the break-in period is typically a specialized lubricant with low viscosity, excellent heat dissipation, cleaning, and antioxidant properties. Some oils even contain grinding agents that aid in the break-in process. Changing the oil too early can hinder the break-in.
