Parking around the trader halo is a continuing issue, especially at Stary. I'm constantly moving multiple vehicles left within 200 meters of the safe zone. It might be a good idea to consider creating a public parking area in the field to the east. It would be as easy as dropping in one of the vehicle garage buildings down next to the road and adding text prompts to the server spam that any vehicles left around Stary need to be there.
As an alternative there could be a fenced in impound lot where offender's vehicles would be placed when they leave them too close. They would have to pay a fine to get them out instead of having to hike all the way to debug. I think most players are just discarding vehicles sent to debug and getting another one anyway.
