Why does the speedometer show 200 km / h and more

The speedometer of all modern cars has a speed mark of 200 km / h or more. A logical question arises: why is this necessary, if the development of such a speed on ordinary roads is still prohibited? In addition, most machines are technically unable to lift that height! What's the catch?

There are actually several answers to this question. And each of them is very important. The first thing to know is that cars available to ordinary people can still reach speeds of 200 km / h and even higher. They can do it (if the engine allows) on special tracks. As, for example, some highways in Germany.

The second important point concerns technology. The fact is that when creating cars, engineers want the speedometer needle to never hit the limiter. This is necessary to prevent the failure of information equipment. Of course, this mainly concerns situations with the same tracks, where the car has the right to accelerate to 180 or more kilometers per hour.

The third point is the issue of ergonomics. Numerous studies show that it is most convenient for the driver to perceive information from the speedometer scale in situations where the arrow is in his left hemisphere or closer to 12 o'clock (in the middle). This feature is associated with the specifics of the human brain and perception.

Finally, there is a fourth aspect - unification. Cars of the same model range can be equipped with very different engines in terms of power. Equipping them with different dashboards, and even more so with different speedometer dials, would just be a waste on the part of the manufacturer when it comes to mass production. Thus, speedometers with unattainable speed are also simple and banal savings on mass car models.
