Yeah same thing last night.. blazing down the hill 42 in a 35. Lady moves up on my tire [ the other lane is open] then changes lanes to pass. Cuts back in front of me, brakes hard, and stops at the signal . I fliter past her less than 5 seconds later.
Her window was down on the passenger side so i asked her if she was in a hurry or something. She stared straight ahead as I rode past her. Silly lady.
I guess they just can't stand the thought of a bike going faster than them
