If someone seems to be determined to chase you down, drive to a police station. 30 years ago I was first in line at a stoplight. When the light turned green, I drove normally but the lady behind me decided I wasn’t going fast enough for her. She pulled beside me and rolled down the window and started yelling. I just kept driving. I then made random turns and realized she was following me. So I drove to our local police station, got out of the car and ran inside. She blocked my car in the parking lot. She took off when I came out with a police officer.
Another time I was on highway 1 going north through the devil’s slide area, into Pacifica then SF. It was nighttime. Someone tailgated me all through the area, obviously pestering me. At a stoplight, I was able to safely but abruptly change lanes to a right turn lane where they couldn’t follow. I turned into a hilly neighborhood I knew well, made a couple of turns, parked, turned off the lights, and ducked.
Fortunately they dropped the chase. After a few minutes I resumed my journey.
It’s pretty scary when someone chases you in a car and you have no idea why.
