Getting into a car is an important part of our driving experience. speedometerIn fact, it may not always provide accurate information. It is necessary to know that this device, which many of us look at with confidence without realizing it, sometimes has a margin of error.

By understanding why speedometers can be misleading drive safely We can also be more aware of our vehicle. To understand why this situation can occur, we need to look at a number of factors.

Factory settings and legal requirements

One of the main reasons why speedometers are misleading is the settings that are set when they leave the factory. Some manufacturers deliberately modify the speedometers slightly to meet legal requirements. It is highly calibrated.

In fact, this situation is that of the driver to avoid exceeding the speed limit A safety measure for. In Europe, there are laws that allow speedometers to display up to 10 percent higher speed. This way, you can be sure that you are not exceeding the speed limit.

Tire size and pressure

The size and pressure of the tires are also among the factors that affect the accuracy of the speedometer. Specified by the vehicle manufacturer of standard tire sizes When using tires of different sizes, the speedometer may give incorrect results.

Same way, tire pressure It can also affect the rotational speed of the wheels, causing the displayed speed to differ from the actual speed.

For example, low pressure tires causing the wheels to turn more slowly, causing the speedometer to indicate a lower speed.

Mechanical and electronic factors

Another reason why speedometers are misleading is mechanical and electronic errors. Speedometers are usually axle or wheels It works through connected sensors.

Faults in these sensors or connection problems This can also cause incorrect speed information to be displayed. In addition, the calibration of speedometers can deteriorate over time, which can cause misleading speed information.

Considering all these points, carefully and consciously You must remember to drive correctly.
