v1.6.1 Release

I. MAIN MOD

1. The majority of pickup trucks and vans have been relocated to standard car storage and will follow standard car spawn rule, which includes:
- 2015-2019 Ford F-150 XLT, including all variants.
- Hummer H2, including both SUV and SUT variants.
- 2008-2013 GMC Sierra (only standard version).
- 2022+ Toyota Tundra XK70
- 2003+ Chevrolet Express (Will have fixed commercial van spawn rate).
- 2016 Ford Transit (Will have fixed commercial van spawn rate).
This should help vanilla traffic spawn more pickup truck models, rather than Chevrolet Silverado 1st Gen, which was the only pickup truck in standard storage by default.

2. All classic/antique vehicles have been relocated into custom car storage and will follow custom car spawn rule. Their spawn frequency has also been reverted to match with add-ons classic/antique spawn rule, and is expected to behave as similarly as possible, which includes:
- 1959 Cadillac Series 62 Sedan de Ville.
- 1970 Ford F-100.
- 1951 Oldsmobile 88.
- 1947–1953 Chevrolet Advance-Design 3100
- 1983-1987 Mercury Colony Park.

3. Chevy Step-van (Company's variants) will now spawn in large cities only.
4. Off-road variant of 2022+ Toyota Tundra will now spawn in rural areas only.
5. 1970 Ford F-100 will now spawn in rural areas only.
6. Adjusted Chevrolet Silverado 1st Gen spawn rate from classic to 20+ years old vehicle. While this model has already been officially released as classic, it is still relatively "young" and more commonly seen than an average classic vehicle.
7. Adjusted Ford F-150 Raptor spawn rate as this high-performance version is significantly rarer. It will now have a 1:5 ratio with the standard F-150 spawn rate in each state.
8. Ford F-150 Super Crew will now have a fixed 1/2000 spawn rate in all states. This is a duty work version and rarely appears in daily traffic.
9. Adjusted 2008-2013 GMC Sierra variants' spawn rate accordingly:
- Duty work variants (Flatbed, crane, etc) will have a fixed 1/2000 spawn rate in all states.
- Utility trailer variant will have a fixed 1/100 spawn rate in all states.
- Camper trailer variant will have a fixed 1/500 spawn rate in all states and will spawn in rural areas only.
10. Fixed bug that makes some trailer car spawn conditions not work properly.
11. Fixed spawn condition error of Chevy Step-van Ice Cream.

II. ADD-ONS
1. Decreased luxury brands' spawn rate by 10% in Texas and Oregon, by 20% in Arizona and Nevada, by 35% in Kansas.
2. Increase luxury brands' spawn rate by 10% in Wyoming, by 30% in Colorado.
3. Changed city spawn condition to tags spawning for antique vehicles. They will now automatically spawn in any large cities defined by the base map or map mod (if other conditions are met and you are lucky enough). A reminder that they will still spawn as standard vehicles in unsupported states.

v1.6 Release

I. NEW
1. Added support for 1 new state: ILLINOIS
- Current Car/UV/Pickup Truck market-share: 36.7%/40.3%/14.7%.
- Adjusted all vehicles' spawn rate. Toyota, Ford, and Chevrolet brands have the highest spawn rate, while rare brands like Maserati, Bentley, etc have very low spawn rate.
- Honda CR-V, Toyota RAV4, Ford F-Series, Tesla Model Y, and Chevrolet Silverado will have a slightly higher spawn rate in their brand due to being best-selling models in 2024.

2. Vehicle trailers diversity (MAIN MOD, JAZZYCAT’S AI TRAFFIC): Similar to vehicles, trailer cars also have their diversity when it comes to each state. This version introduces a rework regarding this matter, aiming to make trailer car spawn more realistically:
- Increased Ram Pickup, Ford F-150, and Jeep Wrangler (all are hook version) from base game by 150% to make them spawn more along trailers.
- Trailer restriction removed: All vehicles with hook can now haul any available trailers from main game or from mod pack.
- Disabled trailers that aren’t from US.
- Mass updated: All trailers have had their mass updated to match their real-life version / general version as accurately as possible. This will also make vehicles hauling trailers accelerate more realistically with the additional weight.
- Weather effect: Certain trailers will now only spawn during nice weather, such as horse trailer. It would be unrealistic to see a horse chilling under a thunderstorm.
- Area Influence: Trailer will spawn accordingly to where you are currently. For example, camper and livestock trailers would appear more in rural areas, while driving near the coast has the chance to catch boat trailers more frequently.
- State Influence: Besides area influence, each state will also spawn certain type of trailer more frequently than others. This difference is hardly noticeable, but it would be once you have driven far enough.

3. Models and specs correction (MAIN MOD): These are some tweaks toward base game AI that I have defined wrong, or have inaccurate/outdated specs information:
- Re-defined Volvo XC40 - Hybrid to Hyundai Kona - 2nd Gen. Specs information and state’s spawn rate have been corrected. This vehicle is now available for only 1.54.
- Re-defined Chevrolet Tahoe - 5th Gen to Chevrolet Suburban - 11th Gen. Specs information has been corrected.
- Re-defined Chevrolet Silverado - 2nd Gen / GMC Sierra - 3rd Gen to Chevrolet Silverado - 1st Gen / GMC Sierra - 2nd Gen. Specs information has been corrected. It will now spawn as a classic car.
- Corrected Ford F-650’s variant specs (Was using general specs for all variants).
- Corrected Temsa 35 bus specs (Was using Temsa 30 specs).
- Corrected 1973-1979 Chevy Step-van’s variants specs (Was using general specs for all variants).
- Corrected Isuzu NPR’s variants specs, including trailer variety weight (Was using general specs for all variants).

v1.2 Release

1. Updated new AI vehicles from 1.54, adjusted compatibility for upcoming Missouri DLC.

2. Vehicle specs updated: All vehicles have had their weight, top speed, and engine power updated/added according to their real-life specs. This should solve the problem of semi/duty trucks accelerating faster than civilian cars, and sporty vehicles that usually have higher horsepower will tend to drive faster as well, making the traffic flow feel more realistic overall.

3. Variant Independent: Variants from vehicles models will now have their own specs, spawn rule, etc and no longer rely on main models.

4. Power-Horsing Vehicles Overhaul: Muscle, Tourer, and Pony class vehicles' spawn rate has been reworked and will be based on their market share in each state. However, their spawn rate still remains low overall, as the state with the highest market share, Texas, only holds 8.9%

5. Classic Vehicles Overhaul:
- All classic vehicles' spawn rates are now based on the number of official classic vehicle clubs registered in each US state.
- All classic vehicles have been reclassified into 2 main categories: Classic vehicles and Antique vehicles.
-Classic vehicles: Vehicles that were manufactured before 2000s, they will occasionally appear on roads, the frequency depends on what state you are currently in.
- Antique vehicles: Vehicles that were manufactured before 1970s, they are much rarer than Classic vehicles, and unlike them, Antique vehicles will only spawn in cities has strong classic vehicle culture, such as Portland, Los Angeles, Phoenix. They will also spawn during nice weather, with some specific models spawn only during certain times of day.

6. Diversity Reworked:
