Plastic hub caps will not fall off when driving on the highway. To reduce costs, many domestic car manufacturers often use steel wheels instead of aluminum alloy wheels for lower-end models, then cover the steel wheels with plastic hub caps. These caps serve no functional purpose other than to conceal the steel rims and slightly improve the wheel's appearance. Drive in the designated lane on the highway: Highways have clearly marked lanes, including dedicated lanes for large vehicles, small vehicles, etc. When overtaking, once you occupy a lane, return to your appropriate lane promptly after completing the maneuver. Avoid occupying other lanes for extended periods. Additionally, the emergency lane should not be occupied for non-emergency reasons. Avoid speeding on the highway: The dangers of speeding are well-known, whether on local roads or highways, as it can lead to irreversible consequences. Maintain a safe longitudinal distance between vehicles on the highway: Under normal conditions, with dry roads and good braking, the distance between vehicles (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, maintain at least 80 meters, and at 100 km/h, maintain at least 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, the distance should be doubled or more. Pay attention to traffic signs on the highway: While driving, always observe roadside and overhead signs and markings. Drive slightly to the right to avoid crossing the right lane divider, providing sufficient lateral space for overtaking vehicles. Avoid fatigue driving on the highway: Fatigue driving is extremely dangerous on highways. When fatigued, a driver's reaction time slows, making it difficult to respond correctly to sudden situations.

Plastic hubcaps can indeed fall off when driving on the highway. Having driven for over a decade, I'm not joking about this. Last time at 120km/h, a hubcap suddenly flew off the wheel - scared me to death! Inspection revealed the clips had aged and loosened. Cheap hubcaps use poor-quality plastic that becomes brittle after prolonged heat or vibration, combined with high-speed airflow pressure making them prone to suction loss. I recommend choosing branded products, ensuring secure installation, and regularly testing for wobble by pushing the cap. Hubcaps aren't just decorative - they protect wheels from stone chips. Proper maintenance saves trouble and money. If one falls off, retrieve it immediately or replace it, as leaving it missing affects appearance and could cause accidents.

Why can't the car key open the door?

The reasons why the car key cannot open the door are: 1. The remote key is out of battery; 2. The car battery is out of power, or there is strong signal interference around; 3. You can use the hidden mechanical key inside the remote key to open the door. If the mechanical key also cannot open the door, it is a door lock malfunction. If the car battery is out of power, the car's sensing system will naturally fail, resulting in malfunction. In this case, the car needs to be recharged. A common issue is the car key battery running out of power, leading to malfunction. Generally, the battery life of a car sensing key is about 2 years. If the battery is dead, the door cannot be opened via sensing. For cars with a one-button start, if the key battery is dead, you can only use the spare key inside the sensing key to open the door.
