Below is more information about car speed: 1. Classification: To suit different purposes, car driving speeds are mainly categorized into spot speed, section speed, and design speed. Additionally, speeds of practical significance include optimal speed and economical speed. The optimal speed is the speed at which traffic volume is maximized on a certain section of the road, used for theoretical analysis of road capacity; the economical speed is the speed at which the vehicle consumes the least fuel during travel, serving as one of the important bases for studying rational consumption of transportation energy. 2. Maximum speed: The maximum speed a car can typically reach is 120 kilometers per hour. The speed of a car should be around 30-60 kilometers per hour when driving in urban areas, generally 80-120 kilometers per hour on highways, and approximately 60-80 kilometers per hour in ordinary urban areas.
