After parking, the dashcam does not need to be unplugged from the power source, as dashcams come with collision detection. The dashcam will automatically shut off after the engine is turned off. Additionally, if it is plugged into the cigarette lighter port, there will be no power if the ACC state is not activated. However, for peace of mind, it is best to unplug it. Below are the functions of a dashcam: 1. Protecting the driver's rights: For pedestrians, bicycles, and motorcycles that cross the road, the dashcam can prevent the driver from being extorted in the event of a collision, serving as effective evidence for the driver. 2. Facilitating the determination of accident liability: In the event of an accident, replaying the recorded footage makes the responsibility clear, helping traffic police handle the accident quickly and accurately. It also allows for the quick removal of vehicles from the scene, facilitating traffic recovery while preserving valid evidence. This creates a safe and smooth traffic environment and ensures fairness. 3. Serving as a deterrent to reduce accident rates: With a dashcam in place, drivers are less likely to drive recklessly, significantly reducing the incidence of accidents. Even in the event of a hit-and-run, the dashcam can capture relevant information about the offending vehicle, greatly reducing hit-and-run cases. 4. Providing evidence for insurance claims: If compensation for traffic accident damages needs to be determined by court judgment, the dashcam can provide evidence, making sentencing and compensation more accurate. 5. Effectively preventing fraud: In cases of professional fraud or roadside robbery, the dashcam can record the scene of the incident and the appearance of the perpetrator, providing crucial evidence for solving the case. 6. Recording life experiences: Many car owners now enjoy self-driving tours and can use the dashcam to document their journeys—whether smooth and scenic or rough and muddy—each experience is a valuable memory.

As a regular commuter, I find it quite important to turn off the engine when parking, especially for economical cars like the Beidou Star. For example, when stopping for ten minutes at the supermarket, I habitually turn off the engine, lock the car, and get out—this saves a lot on fuel costs. Idling can consume one to two liters of fuel per hour, and over time, it adds up to unnecessary expenses. Practicing this habit long-term also reduces exhaust emissions, contributing a small effort to the environment. Additionally, prolonged engine idling can lead to overheating and wear, affecting its lifespan. I've tried newer cars with auto start-stop features, which make it convenient to shut off the engine automatically when parked. But for manual cars, you have to remember to do it yourself—once it becomes a habit, it's no trouble. For short stops like waiting at a red light for a few seconds, frequent engine restarts aren’t necessary to avoid straining the . Overall, turning off the engine when parked is a hassle-free and cost-effective practice.

As a seasoned driver with over 20 years of experience, I firmly believe that turning off the engine when parked is crucial, especially for safety. Whether it's a Beidou Star or any other vehicle model, I always turn off the engine and engage the handbrake firmly to prevent rolling. If the engine is left running, accidental bumps or forgetting to shift gears could lead to dangerous situations. Prolonged idling also accelerates engine carbon buildup and wear, affecting performance and leading to costly and troublesome repairs. I recommend turning off the engine decisively for stops exceeding 30 seconds—it saves fuel and protects the car. Idling a gasoline car burns over ten yuan worth of fuel per hour, which isn't worth it. Modern cars come with auto start-stop systems for convenience, but manual transmission vehicles still on the driver. Safety first—don't cut corners. Make it a habit to turn off the engine in daily driving for a more secure and steady experience.

From a practical perspective, whether to turn off the engine when parking depends on the specific situation. I've driven small cars like the Beidou Star, where it's unnecessary to turn off the engine for just a few seconds at a red light, as repeated starts put stress on the and starter motor. However, if you're stopping for several minutes or more, such as waiting by the roadside, turning off the engine is definitely more appropriate. Turning off the engine saves some fuel and reduces noise pollution, as idling consumes more fuel and isn't cost-effective. Cars with automatic start-stop functions conveniently manage engine shutdown and ignition. The key is not to forget to check the doors and lights after turning off the engine to avoid battery drain. Simply put, keeping the engine running for short stops is fine, but turning it off for longer periods offers more benefits than drawbacks.

From my experience, turning off the engine when parking is highly beneficial for vehicle and longevity. For daily drivers like the Beidou Star, keeping the engine idling while parked leads to prolonged carbon buildup in the cylinders, which not only reduces power over time but also increases repair costs. Shutting off the engine allows components like the fuel pump and cooling system to rest, extending their service life. In terms of fuel efficiency, idling consumes significantly more fuel than normal driving—you can save enough gas for dozens of kilometers per tank. I recommend turning off the engine if stopping for over one minute, while engaging the handbrake for safety. Though modern cars with auto start-stop systems are convenient, occasional malfunctions require manual verification. Developing this simple habit of engine shutdown saves money while protecting your vehicle—a practice worth promoting.

I always pay attention to energy-saving while driving, and prioritize turning off the engine when parked. For compact models like the Beidou Star, shutting off the engine can significantly reduce fuel consumption and emissions—idling for an hour wastes fuel equivalent to half a meal's cost, saving hundreds of dollars annually when accumulated. Long-term idling also increases engine burden, leading to premature aging and affecting driving performance. I make it a habit to turn off the engine and step out when waiting at gas stations or parking lots, using the handbrake to avoid safety hazards. Although modern auto start-stop technology can help, manual cars still best on self-discipline. For short stops like slow-moving traffic, keeping the engine on avoids hassle, but overall, developing the habit of shutting off the engine is wallet- and environment-friendly.
