The series is interesting from the cars and drivers point of view. They have to improve a lot the delimitation of the circuits, I know the budget isn't big and the circuits are temporary, but it have to improve in some way. Those sticks and piles of tires ends always far from the track.
The Punta del Este circuit back in 2017 was the best layout in my opinion.
