Should Vehicle Speed Be Called 'Ma' or 'Mai'?

[VanMorgan]

The unit of vehicle speed is neither 'Ma' nor 'Mai', but kilometers per hour. Introduction to Vehicle Speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with the usual units being kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Vehicle speed can also generally refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Precautions for Vehicle Driving: Avoid racing with other vehicles, drive safely in accordance with traffic regulations, and yield to pedestrians. Do not follow too closely; maintain an appropriate distance by following the right rear corner of the vehicle in front. When overtaking, pass from the left side of the vehicle ahead; avoid overtaking from the right or between two parallel vehicles.
