Many people these days cannot survive in the modern world without a vehicle as a form of transportation. Other than the convenience cars give to a person’s everyday life, it can also be a weapon. It is seen as a weapon because it is a tool that weighs several thousands of pounds but can accelerate to very fast speeds, which gives it a tremendous amount of kinetic energy. This is why reckless driving causes many deaths.
As with any weapon, it also gives people a feeling of power. In a car, they feel safe as they can just drive off. This is why you will often see people driving aggressively and screaming things out the window. Normal people who would otherwise never have the courage to act like that in person, are seen driving reckless and aggressively because they think they are safe from repercussion.
