Who is responsible for vehicle damage caused by road potholes?

For vehicle damage caused by road potholes and injuries to e-bike riders, both drivers and injured parties can seek compensation from the road maintenance department. In the case of vehicle damage, a traffic police accident report must first be issued, after which the relevant responsible department will assume liability for compensation based on the report. Vehicle owners can claim compensation for repair costs, and if the driver is injured, they can also seek compensation under the "Tort Liability Law." More relevant information is as follows: Note 1: In general insurance terms, tires are not covered for separate claims, and the greatest potential threat from road potholes to vehicles is tire blowouts. Some vehicle owners may have the awareness to seek rights protection, but because the loss from a single tire blowout is minor and the claims process is complex, the effort and time required to obtain minimal compensation may not seem worthwhile. Note 2: If there are potholes or pits on the road that have not been repaired in time and lack construction warnings, resulting in vehicle damage, as long as the vehicle owner weighs the potential time and costs involved in the claims process, the approach to rights protection is certain to receive legal support.

Is it harmful to accidentally shift into M gear in a new automatic transmission car?

It's not very good for the transmission gears, but as long as you don't drive at high speeds in low gear for extended periods, the damage is minimal. Here is some knowledge about the M gear: 1. Introduction: After shifting into M gear, the driver can manually shift up or down to control the gear, which is equivalent to driving a manual transmission car. In addition to allowing the driver to experience the thrill of "automatic-manual" integration, the M gear can also play a significant role in many special road conditions. 2. Hazards: Driving in M gear can cause some harm to the engine, as using M gear equals low gear and high RPM, which may result in higher fuel consumption. D gear is the normal driving gear, so it's better to use D gear for regular driving. M gear is the manual mode of the transmission, and after shifting into M gear, you can manually control the upshifting and downshifting of the transmission.

What to pay attention to when buying a used Audi A6

When buying a used Audi A6, you need to pay attention to the vehicle's age, odometer tampering, and the appearance and operation of the engine. Here are the specific details: 1. Vehicle Age: Check the rubber panels on the pedals, as they can reveal the actual age of the vehicle. Worn pedal mats, dirty seats, and scuffed door handles all indicate that the car has been driven a significant distance. If the seller provides seat covers, be sure to inspect the original seat cushions. Many people worry about odometer tampering by the previous owner. You can request the vehicle's recent maintenance invoices from the seller, which should note the mileage. 2. Odometer Tampering: To get a better price, some sellers may give the car a full cosmetic makeover to make it look newer. However, some unscrupulous individuals may tamper with the odometer, turning a car that has driven hundreds of thousands of kilometers into one that appears to have only driven tens of thousands. It’s reported that many auto repair shops offer odometer adjustment services, which can be done in as little as half an hour. 3. Engine Appearance and Operation: Many people assume that a quieter engine is better, but this isn’t always accurate. Instead, listen to whether the engine starts with a loud, crisp sound or if there are any unusual noises. Also, observe if the engine idles smoothly. Start the engine and check the color of the exhaust. If the exhaust is semi-transparent light gray, the engine is in good condition. Black smoke indicates poor engine tuning, blue smoke suggests the engine is heavily worn, and white smoke means the cylinder gasket is nearing failure.
