Can a car's odometer be adjusted?

[DeCamilla]

Car odometers can be adjusted. Here is relevant information about car odometers: 1. Composition of car odometers: A car odometer consists of two gauges, one being the speedometer and the other the odometer. 2. Principle of car odometers: The diameter of car wheels is known, making the wheel circumference constant. This allows calculation of how many rotations the wheel makes per mile traveled, which is also a constant. Therefore, by automatically accumulating the wheel's rotation count and dividing it by the rotations per mile, the traveled distance can be obtained. New car odometers include two roller counters driven by the same flexible shaft, recording trip distance and total distance respectively. The trip distance typically has four digits for short-term counting and can be reset; the total distance has six digits and cannot be reset.
