This is interesting but usually game sounds focus on how u hear it on onboard cameras/TV cams. So also our sounds are mad how u would hear it without wearing a helmet and earplugs. About the wind noise: I have talked with many racecar drivers and usually there is a lot of wind inside the car (depending on the car for sure) Racecars doors and windows are lightweight. Some real drivers told me, at higher speeds, there could be a gap in the door and u have loud wind noise. In the sim it is also a bit of a speed feeling thing to have an exaggerated wind noise. Same with squealing tires, louder in sims to help the drivers hear when tires are over the limit. As a sound dev, it is very difficult to find the balance between realism and what people want/need.
