Sorry for the delay in replying. Yeah, I calculated the FOV using an online calculator. None of them are suitable for projector screen sizes but you can divide the screen size and the distance by the same amount to scale down. In this case I've halved the screen size and distance:

This gives a vertical FOV of 26 degrees. This looks like this:

I can go up to 32 degrees and still look ok though:

So the perspective sort of looks ok I guess. But the scale is still off. Like if I had the drivers arms on his hands would be twice the size of mine.
I don't know if the geometrically correct FOV is actually correct in all cases.. With a screen this big it would be good to get some more peripheral vision.
