Is ETC Mandatory?

ETC is not mandatory. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will remain at highway toll stations, and vehicles without ETC will have to pay tolls manually. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During holiday free-toll periods, ETC users can still use highways, and passing through ETC lanes will not incur charges for those who have already installed ETC. ETC Billing Principle: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's onboard electronic tag (installed on the windshield) and the microwave antenna in the ETC lane, the system uses computer networking technology to settle payments with banks in the background. This allows vehicles to pass through toll stations without stopping, achieving the goal of seamless toll payment. All of this operates on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions since vehicles don't need to stop at toll stations; Cost-saving: Reduces vehicle wear and fuel consumption by minimizing frequent starts and stops. Users also enjoy a 5% discount on toll fees; Improved efficiency: ETC lanes can theoretically increase traffic flow efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, key city clusters should achieve interoperability of transportation smart cards, and the proportion of vehicles equipped with ETC should significantly increase." It also set a target in the "13th Five-Year Plan" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." Future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC adoption for trucks. There will also be exploration into deeper integration between ETC systems and smart transportation directions like vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC in the future.

What to Do If a Small Spot of Car Paint Chips Off?

Here are the steps to repair a small chipped spot of car paint: 1. Clean the repair area with a towel, wrap sandpaper around a sponge holder, and use water to smooth out any raised areas; 2. Fill the dented area with putty. After the putty dries (approximately two hours), use sandpaper with water to sand the filled area; 3. Use masking tape to cover areas that should not be painted with newspaper or tape, prepare for painting, and test the color by attaching the paint pen to the spray can; 4. If the paint pen solution is too thick or the color is too dark, use a straw to add thinner to the paint pen. Pay attention to the color transition when spraying; 5. Prepare clear coat, remove the paint pen and straw, replace with a new straw, and attach the clear coat to the spray can; 6. Spray the clear coat on the repaired area, wait for 1 to 2 minutes, then remove the newspaper or tape to complete the repair.

What is the difference between DS4S and DS5?

DS4S belongs to the compact hatchback category, while DS5 is a new-generation luxury crossover model. Here are the specific differences between the two models: 1. DS5 is an upgraded version of DS4S with more abundant power configurations. It embodies the identity of a coupe that combines power and sensibility, a versatile hatchback sports tourer, and a premium sedan. 2. The body dimensions of DS4S are slightly larger than other hatchbacks. Its front face design inherits the family-style elements, featuring clean lines and appropriately placed chrome trim that conveys a sense of dynamism. 3. DS4S adopts a six-speed automatic transmission supporting multiple driving modes, enhancing driving control experience and adding fun to driving. The intelligent start-stop system is more reliable and energy-efficient.

How to Check the Tread Depth of Car Tires?

Methods for checking car tire tread depth: 1. Prepare a tire tread depth gauge; 2. There are a total of 6 triangular symbols around the side of the tire. Following the direction indicated by the arrows, you can feel multiple raised ridges in the tire grooves; 3. Insert the tip of the gauge into several main treads in the same cross-section of the tire surface to measure the depth. The braking, acceleration, and steering between the tire and the ground are all achieved through the tread patterns on the tire. The tread pattern has a significant impact on the tire. The deeper the tread, the greater the elasticity generated between the tread and the ground, resulting in stronger grip.

What is the 0-100 km/h acceleration time of the Phantom?

The Phantom's 0-100 km/h acceleration time is approximately 5.3 seconds. The 0-100 km/h acceleration refers to the time taken to accelerate from 0 to 100 kilometers per hour, which is a direct reflection of a car's power performance. Here is some relevant information: 1. Various factors such as ambient temperature, road conditions, vehicle wear, and even the amount of remaining fuel in the tank can affect the test results. 2. Generally, 1.6L compact cars have a 0-100 km/h acceleration time between 11 to 13 seconds, 2.0T midsize sedans between 7 to 8 seconds, while supercars mostly achieve acceleration times under 3.8 seconds. Among vehicles with the same displacement, those equipped with turbocharged engines have a significant advantage in 0-100 km/h acceleration due to their stronger power output and a very wide maximum torque range, allowing the vehicle to achieve maximum acceleration capability at very low RPMs.
