Some people are terrified of spiders, yet have no fear of cars. This seems illogical since cars are potentially more dangerous than spiders, and yet it seems spiders are feared a great deal more.
Even so, millions of people still feel anxious when they are driving, but on different levels. For example, some people have a fear of riding in a car while others only have fear while they are driving as a means to keep them safe and out of harm's way.
Furthermore, some people have attacks while they are in the car, but do not necessarily fear the car itself. All of these are considered different types of car anxiety and require various methods to treat them properly.
