I think the current structure of rivals needs to be revisited. Yes we can change tire compound but currently we are forced to compete on a permanent full tank of fuel. That full tank of fuel completely changes the handling mechanics of the cars ie excessive understeer. I’m not aware of any Motorsport where the drivers try to post their fastest lap while still on a full tank. Since the mode is all bout the fastest lap possible then the cars should be placed in a qualifying trim, that being soft tires and lowest fuel level possible.
Alongside those changes qualifying laps in online multiplayer should count towards rivals or a leaderboard of some kind. Since everyone else on the track is ghosted there would be no way for someone to cheat with drafts or tows down long straights to better their times. That would give people more of an incentive to participate in qualifying with the possibility of posting their fastest time ever while simultaneously placing high on the grid.
