How can beginners judge the distance between cars when driving?

Methods for beginners to judge the distance between cars: 1. When the upper edge of the rear bumper of the car in front is visible, the distance is 1 meter, and you must be careful to maintain this distance; 2. When the lower edge of the rear bumper of the car in front is visible, the distance is 2 meters, and you can slowly adjust to a suitable following distance; 3. When the lower edge of the rear tires of the car in front is visible, the distance is 3 meters, and you can follow a bit closer, as being too far might invite other cars to cut in; 4. When the car behind fills the right rearview mirror, the distance between the two cars should be about 3 meters, but when the car behind fills the left rearview mirror, the actual distance is only 1 meter; 5.

Does converting a gasoline car to natural gas have any impact on the vehicle?

Converting a gasoline car to natural gas does have an impact on the vehicle, which may result in reduced power output. Below are specific maintenance guidelines for CNG-converted vehicles: 1. Equipment maintenance: Regular maintenance of the CNG system is required. Due to the special properties of the fuel, a comprehensive leak inspection of the gas tank should be conducted every two weeks. 2. Driving habits: Before daily operation, in addition to the checks specified in the original vehicle manual, inspect all pipelines for cracks or fuel leaks. For short-term parking, always turn off the main power switch and the CNG cylinder valve. Also, ensure the vehicle is equipped with fire extinguishing equipment during normal operation. For long-term parking, the CNG should be completely depleted. Never service the fuel supply system in enclosed garages or workshops.
