The Cooperative Principle of Freeway Driving's main objective is to encourage drivers to interact and cooperate with other drivers in a way that will allow traffic to flow freely, which is the antithesis of defensive driving "Actually our concept of freedom today is essentially a negative one. It is freedom from and not freedom to, because we are mostly concerned with what we are against and not what we are for - against whom we should defend ourselves rather than what we are living for."
-Erich Fromm
