Psychology says people who decorate their car's interior with soft toys, cushions, lights and others aren't necessarily doing it to impress other people. A car is often treated as a practical object used to travel from one place to another. However, some people change the interior by adding soft toys, cushions, lights and other personal items. These additions can make the vehicle feel more familiar and comfortable. The behavior can also provide a sense of control over a personal environment. From a psychology perspective, the practice can be linked with emotional comfort, self-expression, stress management and the way people attach meaning to their possessions.
