What is the appropriate tire pressure for highway driving?

When driving on highways, the tire pressure should be inflated to around 250 or 260 Kpa. Generally, a car's tire pressure should be maintained between 220 to 260 Kpa. If the tire pressure is too low, it can easily cause excessive compression and deformation of the tire cord layer during high-speed driving. As the speed increases, it may even lead to the phenomenon of standing waves in the tire, and in severe cases, it can cause a tire blowout. Therefore, it is essential to ensure that the tire pressure is adequately sufficient when driving on highways. Strictly speaking, tire pressure refers to the air pressure inside the tire. In car maintenance, the engine plays the role of the car's heart, and engine damage can lead to the end of the car's life; tire pressure symbolizes the car's blood pressure, and the level of tire pressure has a significant impact on the car's performance and power. Air pressure is the lifeblood of the tire, and both excessive and insufficient pressure will reduce the tire's lifespan.

What do the markings on tires represent?

Taking 205/55R16-91V as an example, 205 refers to a tire width of 205 millimeters, 55 indicates an aspect ratio of 55%, R stands for radial tire, 16 denotes a diameter of 16 inches, 91 is the load index, and V represents the speed rating. Below is an introduction related to tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For instance, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low during that period. Since tires can also age when left unused for extended periods, it's important to check the production date when purchasing new tires.

How does vehicle traction change in tunnels?

This is within the scope of the Subject 1 exam. In tunnels, there is no sunlight exposure, resulting in lower temperatures and stronger water condensation effects. Consequently, the road surface inside tunnels tends to be damp, leading to reduced vehicle traction. Below is relevant information about Subject 1: 1. Exam Introduction: The driver's license Subject 1 test assesses theoretical knowledge, conducted at the vehicle management office, and is a mandatory licensing exam for applicants. The exam content includes fundamental driving theory, road safety laws and regulations, traffic signals, traffic rules, and other basic knowledge, along with local regulations. The scheduling of the driver theory exam is arranged by local vehicle management offices. 2. Exam Process: The total duration of the Subject 1 exam is 45 minutes, consisting of 100 questions in the form of true/false and multiple-choice questions, with a perfect score of 100 and a passing grade of 90. The exam papers are randomly selected and compiled by the computer driver examination system according to the proportion specified in the "Motor Vehicle Driver's License Business Work Specifications."

Does Tesla Have Eavesdropping Capability?

Tesla does not possess eavesdropping capability. Below is relevant information about Tesla's in-car camera: Responsibilities: Generally, in-car cameras primarily serve two functions. Firstly, they perform facial recognition to verify the driver's identity, with more advanced versions also matching driver preferences accordingly - essentially functioning as a sophisticated version of smartphone Face-ID. The second main function is serving as part of the driving assistance system, where the in-car camera detects driver drowsiness and triggers an alert. Such "fatigue monitoring" features are widely adopted among traditional automotive brands as well. Purpose: According to OTA information, Tesla's in-car camera serves dual purposes - it supplements blind spot images for the vehicle while automatically recording images and short clips prior to collisions. On one hand, it monitors driver attention during Autopilot operation; on the other hand, it supervises passengers after Tesla's car-sharing implementation to prevent malicious vehicle damage.
