What do you do when someone is tailgating you dangerously close, on a high speed road. You know they cannot stop in time if there is an emergency, or you have to slow for traffic in front of you. People drive like they are completely crazy now. I drive the speed limit, and everyone passes me. In the above case, if on a multi lane road, I change lanes. On a two lane road, I thank the instructors of the two pursuit driving courses I took. They may just save my life.
