There are people who can see things from a psychological point to view and this is definitely something that can be very interesting. For example, window tinting for cars makes people inside the vehicles feel prospected and invisible, but they also seem to feel like this adds a level of classiness to their vehicle and mystery to their presence.
Window tinting has become something that is about much more than just the protection, but also the look of the vehicle and the personality of the driver. That is why there is a cultural power to window tinting that is extremely popular in many areas of the world.
