There are cornering tests for the red markers in which a die is rolled to determine the outcome referenced against a driver’s skill points. It’ll all become clearer once I releases the first draft of the instructions. I don’t have the knowhow to to that but if anyone else fancies a try then it’s entirely up to them. I did consider chance cards but they would be hard to implement without copying other racing games; one I remember has a mechanic which generates a chance card for every pit stop made. I like the idea but would want another way to implement it. As for the pit, it’s already a longer detour which will be necessary to enter at certain points during the game. I don’t know if you noticed the draft track above as it doesn’t feature squares but circular markers.
