This might sound a litle extreme, but in fact is not: a proper distance between you and the other vehicles on the road is a matter of live or die. So, why take the chance? Do never allow your self to get "boxed in." A proper space creates time and helps you avoid collisions. Maintain at least two seconds of following distance, more if posible. Adjust your position in traffic as necessary to avoid driving in others’ blind areas. Don’t allow yourself to be tailgated-change lanes or adjust your speed to encourage tailgaters to pass you.
Advanced driving or defensive driving is a form of training for motor vehicle drivers that goes beyond mastery of the rules of the road and the basic mechanics of driving. Its aim is to reduce the risk of driving by anticipating dangerous situations, despite adverse conditions or the mistakes of others. This can be achieved through adherence to a variety of general rules, as well as the practice of specific driving techniques.
