Discription of Events: I am writing to formally report an incident of reckless driving and aggressive behavior on 6/17/2025 at approximately 830pm involving a driver operating an older Honda Pilot with Michigan license plate DGU534. I was driving southbound on Newburgh Road, just north of 7 Mile Road, exiting a subdivision. Due to road construction at 7 Mile, only one lane was open. When the light turned green, the vehicle in front of me (license plate DGU534) did not proceed, so I gave a honk to alert the driver. After that, the driver began behaving erratically. She proceeded to slam on her brakes multiple times in an apparent attempt to intimidate me. After we passed the construction zone south of 7 Mile, the driver rolled down her window and pulled alongside me, shouted aggressively and repeatedly made obscene hand gestures toward me. She then attempted to pull alongside my vehicle multiple times, continuing the same disturbing behavior. Roughly a quarter mile further, the driver accelerated past me at an estimated 50 mph (I was driving approximately 40 mph), then repeatedly slammed on her brakes while laughing hysterically as I approached her from the left lane (she was in the right). Her behavior was erratic and extremely dangerous and I feared for my safety. I am requesting that this matter be looked into. This type of aggressive and threatening driving creates a serious risk to public safety. Her description from what I could tell since she was wearing a ball cap and sunglasses was that she is appx 30-40, shoulder length brown hair and clearly unstable.
