I had a woman do the exact same thing to me in a construction zone where the lane she was in ran out. She kept creeping towards my truck (I wasn’t going to let her in) until she was about 2 inches from my truck. I let her get in finally because I didn’t want to deal with the fender bender and honked my horn at her. She stuck her middle finger out the window and started cussing me out like I had done something wrong to her. The traffic was real slow and down to 2 lanes and when I would try to pass her she would move into the lane I moved into and drove real slow. When traffic opened up I got beside her and called her every name in the book and she got off at the next exit.
