How are they gonna decide who goes out first, and in what groups??? Lots, Champoinship Standing or a paddock lottery.
What id do is have a 1 hour 20 muinite open session. Where every 15 mins the slowest 5 at that mark get knocked out, if they are on a fast lap at that point, tough luck they ran out of time. The final 6 drivers get a 20 minuite session that is the fastest to pole session, where, this session has the if youre on a fast lap and the checqured falls, you can finish it.
But id make it that you have to complete a minimum ammount of laps each session, say 6 each session, meaning that the maximum of cars are out on track at any moment. And the penalty for pole is engine milage, say 30 laps plus for the final 6 drivers.
Got to give the guys that gain pole a dis-advantage some where. Id also make each driver have 2 sets of options and 1 set of primes for this session, meaning that tyre management is crucial as well.
That should really beef up the "for the show" element.
