📋 About This Mod

Traffic Expansion Pack

A mod that greatly expands upon the highway traffic in My Summer Car, aiming to increase the variety and intelligence of AI cars.

This mod may not work properly with MOP (Modern Optimization Plugin)! Issues with invisible traffic cars are caused by MOP so if you experience invisible cars then I recommend removing MOP, bug reports about it will be removed.

Features
  • []30+ unique car models

    []Many completely new custom, lore friendly car models

    []Completely randomized highway traffic (randomized car models, colors, license plates, wheels, drivers, passengers etc. Some cars even have multiple body styles or trim levels they can spawn in!)

    []Much more variety in traffic cars compared to vanilla My Summer Car

    []More intelligent AI that will crash less and be safer in general

    []Cars will attempt to stop to avoid hitting stopped cars in the road

    []Cars are aware of warning triangles and will try to pass them safely (most of the time)

    []Cars will use turn signals on overtaking, hazard lights in emergency scenarios and reverse lights when reversing. Most cars also have license plate lights

    []Randomized traffic density - sometimes the highway traffic will be lighter, other times there will be more cars on the highway

    []Much lighter traffic density at night time

    []Traffic is reset and re-randomized every time the Player enters the highway or sleeps (optional)

    []Some cars can spawn with trailers

    []Some rare-spawning unique NPCs, including new Amis cars and other dangerous drivers

    []Drivers will sometimes flash their headlights to warn you of upcoming police checkpoints

    []Cars will sometimes turn into the Peräjärvi town area (for fuel or just to drive around)

Notes

[]This mod almost completely replaces the vanilla highway traffic! (only bus and Amis cars are kept vanilla)

[]You may encounter a small lag spike when entering the highway, caused by the cars spawning - if this bothers you, you can disable "Regenerate cars everytime highway is entered" setting but note that then traffic cars will only be spawned once and will stay until the game is reloaded, Cars wont be re-randomized so you will see less different cars

[]If you have a weak computer this mod may affect your performance due to increased amount and complexity of the traffic cars. You can reduce the amount of maximum cars that
