I was litle thinking abaut Heat-1 and Heat-2 and I think that is good idea , but it must to be 3 or 4 laps with all the 8 top drivers from qualy, not 2 laps , with mandatori pit stop , to force the racers to choose when he want to use a pit stop, and offcourse mandatory tyres change . Let˛s call this period just HEAT .
This is my sugestion.
