I suggest you compare, as others have shown in this thread, the perspective is identical...
(have you ever thought why PD would move the position? Makes no sense, but removing layers does, and also is very easy from a software perspective ( yes, I'm a software engineer, so know about this stuff too))
But believe what you want to, I think it's important we just look for ourselves,
I suggest you compare first...what I said before are comment after compare.
here the pics in 4 different view setting.
This is bumper view,the focal length seems equal to standard cockpit view.
but the cam is install on the bumper centre, so the object in front are little bigger than standard cockpit view.
Standard cockpit :just like bumper view have wide angle cam. but the position is different, little behind the bumper view and sitting on left side,so
we can see the object position & distance in front have little bit different.
NARROW COCKPIT, the cam position is the same with the standard,
but in different focal length. less viewable area, also less perpective distortion.
Narrow cockpit view 2, also in the same cam position with other cockpit view,but have a focal length that nearly equal to human eye vision.
much less viewable area because of no wide angle distort and the limitation of the 16:9 screen.That's why the head tracking function here,(but sadly just function in arcade mode...)
In Bumper view or the standard cockpit view, object have being distort ,
the feeling of the distance are increase because of the perspective distortion.
object seems moving faster, this is good for game playing, that's why
most of the racing game are using this treatment.
In the Narrow cockpit view, object surrounding moving seems much slower then all the other cam setting,
this is because we can't see the left and the right section on the screen.
In the real life situation,just like add a mask frame in front of you to driving.
but if we can add two more screen on both side just like GT4,
we can get back a complete speed sensation.
If we talking driving simulation, a human vision simulation is a must.
That's the different.
