The questioon rised when, driving the Lotus Exige S, I noticed that the FOV of that car was much narrower than any other car I driven before.
So I will try to play a bit with the settings of TDUF. Maybe I will be able to find the exact setting and, even, make a comparison between the effect it has to the actual FOV values.
EDIT/UPDATE
Looks like @Djey was right. Binoculars is, indeed, the value that controls the FOV of the game. I've tried messing with the visual of "Ferrari LaFerrari", and got curious results. You need just small variation to the value to obtain relevant results, and going more that 100 units at a time breaks the FOV or simply starts all over again (obtained similar results with 16650 and 10000, for example).
Now I need to now how to relate the "binoculars" value to actual FOV degrees units. If someone has an idea, pleas share. Maybe I will create a dedicated post in the mod section, since this matter was never talkend in the forum about TDU, but just TDU 2 (that has a little mods that does the job)
Here's the results I got messing with it:
