in the game managers can change the aggressiveness of drivers and this impacts tire wear, engine wear, fuel consumption and tire temperature. could change that and put two options, one for rider aggressiveness affecting tire temperature and tire wear, and an option for engine aggressiveness affecting engine wear, fuel consumption and maybe even tire temperature already that on the straights is where they heat up the most. this would make the fuel and tire wear calculation more valuable and at the same time it could make managers more wrong as the fuel calculation would be much more important.
could also increase fuel consumption aggressively if you accept my suggestion.
