I think that small changes keeping the idea of the strategy may make this game better and more difficult.
- First: When u chose an ammount of fuel, that fuel will be added to the deposit, instead of filling the deposit until it reach that ammoun, like now. This way u can start with all the fuel to save time in future pits stops (althought it probably wouldn't benefit you), also calculation mistakes will be carryed all along.
- The oportunity to put "conditions" to enter pit lane or directly chosing the lap, more than just letting the system/driver decide when to enter when he gets out of fuel or tyres, in pre-set strategy,
- Chance to choose to "mix" the rain-stop with a regular pit stop, and adding fuel.
- Limited ammount of tires, built with "car parts", if u don't get enought, the tyres start in a worse condition.
- Changes on wing set-up and PL during pit stops (in live or, if enabled by you in strategy, by the driver), .
