Before entering mass production, each car undergoes high-speed tests on special tracks. Today in the new exciting online game Idle Treadmill we invite you to do just that. In front of you on the screen you will see a special mechanism that will consist of a bunch of treadmills. By clicking on them with the mouse, you will have to bet on each car that will drive along it picking up speed. This way you will test the car and get points for it in the Idle Treadmill game. On them you can upgrade the tracks and open new car models for testing.
