The default traction configurations need really need tweaking to suit Livonia's hilly terrain.
It's ridiculous that an FWD Gunther can't make it up the hill on a tarmac road without tacking like a yacht ! And that the Ada 4x4 barely makes it up the same hill.
It seems they still have their Chaernarus traction values.

These cars were presumably owned and used every day by the local populace, so their configs should match the terrain requirements.
