So I booted up the traffic system on Italy, and the first things that spawned were a Firwood Police Bluebuck, Detective Moonhawk, and a Bolide. After more runs of different traffic sets and switching maps, it appears that there seem to be two lists that the game pulls traffic from, one of traffic vehicles and one of police cars. Obviously, that leads to numerous situations in which traffic spawns vehicles that make no sense whatsoever for a map. There is a very simple solution to this issue, every official map (within reason, no gridmap, cliff, or template obviously) should have it's own pool of police cars and traffic cars. If a map is not one of these maps, the current system would be implemented in which it chooses completely random cars. Not a super complex suggestion, but one that would make the game far more immersive.
