The authors of the Novate.ru site have more than once considered such features of the structure of the car, which even experienced drivers cannot explain. And in this article we will find out why a thin strip is applied to the mirrors on some machines. And this is not heating at all, as one might immediately think.
Some drivers, especially owners of foreign cars, are haunted by one question. Every day, while driving, they look in the rear-view mirror and constantly see one small, seemingly small detail. A clearly visible vertical line extends about 1/4 of the edge of the mirror. This design nuance can be seen both on new cars and on cars of the late 90s. What is this?
Someone can tell right away that this is visible from the mirror heating line. But this is not the case. Moreover, the heating element is mounted in a mirror in a completely different way. To the same, not all machines "with a line" have this option at all.
To understand the need for the mysterious line, you need to carefully examine the car mirror from a short distance. As you know, for a long time it has been made with a curved profile, which makes it possible to increase the viewing angle backward. But the perception of distance is seriously affected. If you make the mirror a "sphere", then the view is improved, but the distance to the cars behind it will be difficult to determine. As an exit, about ¼ of the mirror, closer to the outer side, is made curved, i.e. "Long-range", and the main part - remains ordinary, flat.
This design helps well both on the highway and in the city, because now the driver sees the "blind spots" of the car much better.
By the way, this is not the first time that the topic of non-standard car mirrors has been raised on Novate.ru. We have already figured it out earlier why on German cars the right mirror is much shorter than the left one.
