Back to the original question in the thread title. The answer is ego, arrogance, and narcissistic behavior.

Ego: How you feel about yourself. Nothing wrong with an inflated ego.

Arrogance: How you ego drives feelings about others. One could argue that true arrogance is more driven by low self esteem rather than an overinflated ego.

Narcissistic behavior: How arrogance tends to manifest itself through poor behavior. The narcissist can only gain a temporary sense of self worth by ensuring that others are beneath him. Key being temporary, hence the ongoing behavior.

Sad, but what else would you expect when you combine car enthusiasts and the occasional arrogant narcissist?
