A month later I have the 100 hours in the game, only one Sport win (boy did that feel good), a few poles and fastest laps. I spend most of my time in the online lobbies though.
I think I would get more wins if I switched on aids or drove in 3rd person view - but I play against myself with a wheel and love driving.
I do not understand all the fuss about single player mode, since online gaming existed I have not bothered with single player modes or campaigns in any multiplayer capable game, with the exception of GTA5. There is just no satisfaction whooping AI. For people wanting their single player ego boosts - there are custom races.
