Mercedes-Benz

Cars are not only a common mode of transportation, but also a source of danger. With the ever-increasing number of vehicles on the roads of Turkey and the world, increased travel speeds inevitably lead to more accidents. Therefore, the designer’s job is to make a car that is not only comfortable but also safe. Passive safety systems can help solve this problem.
