I guessed the "Tractive Effort", but thought it could probably relate to lateral acceleration. Hmmmm, it's not colcob's program, yes, I need to say an idea to understand it, lol.

Try this layout. Everyone has to start from the grid, and then pass 3 checkpoints. During a lap the drivers will have to drive in reverse direction, so this will require everyone to be careful and follow the traffic regulations (and also to agree with left or right side driving
)
