There is no well-established universal parking code in which a hanger attached to a vehicle means “don’t park here,” “this car is being watched,” or something similar.
If someone parked next to this vehicle and noticed the hanger afterward, it would be understandable to wonder whether it was directed at them. But without additional evidence, that would be speculation.
The Most Likely Answer
So, is the driver a “psycho”? Probably not. 😄
