In the real world, the one being simulated, one doesn't change their eye lens to make the road stretch out in front of them, but seating position nearly always needs adjusting.
BTW
@Johnnypenso, I'm using a DOF in AC of 29 presently, and there are a number of cars where the guages are just not visible and can't be brought into view. I must say I am very happy with this as it fits with my particular distances and equipment. But the biggest and most important factor in it all is do the cars in front of me look the correct size just as they would in real life. Now I have that setting my experience has been revolutionised and is so much more immersive.
