1. Weather -- Yeah, wet weather is tough, at some tracks practically impossible. Qualifying is worse, bad enough that I see rain forecast for a quali session then i figure that's a good opportunity to take a set of engine components if need be. Once upon a time I liked an occasional wet race because it was possible to compete with the AI. I think the AI just needs to be nerfed a bit.
2. The fuel usage on the race strategy screen isn't calibrated correctly once you start making fuel consumption upgrades. Pay attention to the amount of fuel you're burning in free practice and in the race strategy program and fuel accordingly.
3. The AI can be a bit sporadic but I don't think there's a better AI in any other racing game.
4. Difficulty levels are wildly different from track to track. I'm as competent at Bahrain as I am at Japan, Spa or a few others, yet i have to set the difficulty level 10 clicks lower there to be competitive.
They have a mountain of time trial data that they could use to normalize the AI performance to actual human ability.
