After 38 years of driving, I still don't know how to handle the psychotic maniacs who literally come out of nowhere and ride my rear bumper---on the highway(!) It happened twice in the same area in the last week (405 becomes 518 west towards SeaTac airport), and on the exit ramp last night. Other than those a__holes, I really enjoy driving. I guess they think that they are invincible, have no regard for others and that you are on their road?(!) How do you handle them? Thanks.
