Thought I'd start a thread about career mode, after I spent quite some time learning that turning off replay right before you do the first wet race is perhaps not a brilliant idea.  You might want to keep replays on until you learn how to drive Sebring in the rain.

Key tips:

• look for puddles and see if you can avoid them, and if you cannot, consider slowing down
• don't think you can drive the track as fast as you can in the dry
