All vehicles have been reclassified according to their proper segment (Compact to Full-size, Muscle, Pony, etc.) and type (SUVs, Passengers, Pickup Trucks).
All vehicles' spawn rates have been adjusted, with the ratio based on brands' market share and the model popularity itself.
Realistic vehicle specs make AI acceleration and speed look more natural.
Diversity between classic, modern, and sport vehicles with add-ons, helps improve the AI spawn to be as realistic as possible.
Some rare vehicles will now actually be "rare" and would need ideal weather, time, etc conditions to catch a sight of it.

Added support for 1 new state: ILLINOIS

This update marks the end of the diversity rework process. 
Balancing will occasionally come to adjust the spawn rate of some vehicles, but a major change won't likely come in the next couple of months until some states release their quarterly report. 
The mod will now shift back toward the original plan with focusing on adding support for other states, more AI pack support, realistic coloring, etc.
