What does VehicleMapId tell me?

[Bull]

I noticed some of the order tracking posted here or saved on the google spreadsheet contains a VehicleMapId. What does VehicleMapId actually tell me? I have a VIN, does a VehicleMapId add anything?

No one knows currently. Someone started tracking it to try to identify what it means, but right now it's up in the air on what sort of identifier it is.
