The two cars were separated by roughly forty minutes.
The passenger in the first car said that when he went to look, there was no snow on the car. He touched the area near the engine and could still feel some warmth. He guessed that a self-driving tourist went to the Old Forest to have fun, and he didn't pay it much mind and just left.
When the second vehicle passed by, there was a thin layer of snow on the car. They also got out to look; all three cars were checked, but there was no one inside, and there were luggage and food left behind, so they guessed they must be tourists.
They even specifically went into the forest to have a look for a while but didn't find anyone. When passing the checkpoint, they informed the staff there about this matter and suggested they pay attention to those three cars.
The passengers in the second car even took photos, and they specifically wiped off the ice and snow on the license plates for the picture.
