I very much agree with the above two players on the C-D speed limit. Some players do drive at a speed of 110KM/h on the C-D, which will make them dangerous drivers. At the same time, they are also forcibly overtaking when overtaking. Whether they are overtaking or not, or when they are overtaking, they will turn rapidly when they meet the opposite car, which will cause normal players driving in this lane to be forced to take emergency avoidance measures to avoid accidents. Sometimes, if you can't avoid it, it will also change from a small accident (2 cars colliding) to multiple accidents and serial accidents (more than 2 cars). In addition to the current winter module, some players will definitely install physical modules, driving Skoda or the front of the car, one foot brakes down, will definitely not be able to stop the car and will skid, which will affect the rear car, including the anticipation of the skidding vehicle when the car is approaching (a series of safety issues such as braking distance).
