There's no way to fix this, no change with patch 1.3, it's still just as overexposed!
They need to actually disable / remove the culprit (auto-exposure) on their end, not tweak it for a couple of locations like they said they did. It's still active all over the game and is completely unrealistic with how the game is suddenly overexposed when you move the camera behind the windshield, and it's still a problem in every location, not just the brightest ones where it's the most obvious.
They implemented the feature all wrong, it should only be tied to some actual parts of a stage like the tunnel in Monte Carlo. NOT THE CARS THEMSELVES. It should be very simple for them to actually remove auto-exposure / eye adaptation entirely on their end, this needs to be hotfixed and taken out asap.

Don't care if the whole game has to be re-downloaded it because of their stupid mistake when building the game and how that junk wound up being wrongfully applied to all car interiors. If that's what it takes, that's what it takes. Do it right it this time, EA & Codemasters.
