Whenever other motorists are driving to close to my car and I am in the correct lane and doing the speed limit (keeping in mind the weather/road conditions) I just "stand my ground" and let them pull ahead of me.

If these drivers are making you anxious while you are driving I would recommend that you talk to your therapist so you can better manage your anxiety while driving. Because simply pulling over and letting them go by doesn't appear to be easing your frustrations or anxiety.
