At Melbourne, is the guy running in front going to have to conserve fuel later and is the guy behind conserving his fuel at the moment?
I think we are all in danger of underestimating the engineering and especially engine management software.
I dont think the driver will be doing that much calculation or decision making beyond selecting modes.
For example he might start with a mode calculated to get him to the end of the race at an optimum fuel usage and power output. as the race goes on depending to his actual % of using that mode, he can then change modes/profiles.
I really dont think they will be lifting and cruising like LMP which is more endurance. F1 with the low speed corners and constant acceleration/decceleration wont be the same. The drivers will still drive to the max all the time, its just that the max will be dictated by the particular engine mode selected.
So one guy could have his foot flat down and his teqammate has his foot flat down and flys past him - because of the different engine modes. I dont think one of them will be thinking 'I have 23 kgs left, let be depress the pedal 77.34%
I could be wrong, but everyone seems to be thinking the drivers will make a difference by gentle pressing a fly by wire pedal, which is ridudiculous really
