Well, this is quite strange. You can streetview the stretch of the highway where Carlee pulled over. It’s right by/before a sign for Hoover/Bessemer and after a blue food exit sign with Waffle House in the top left corner.
There are shots from Jan 2023 which shows a gray car pulled over almost exactly where Carlee pulled over. Most likely coincidental, but if you track the street view movement, the car suddenly appears, so parked in that spot as the street view vehicle was approaching the area. I tracked back looking at oncoming traffic and could not see that same gray car heading towards the area on the interstate
Screenshots attached of the car not in frame, and then in frame in the next jump in movement, and screenshots looking back right before the jumps where the car appears.
Other notes that I see in steetview however, the ditch is much more narrow than I thought from the traffic cam video.
