22" 16:10 screen at about 28": 58-65 degrees approximates reality.
The "feel" of it is in the view of the track, other cars, and trackside objects - tune for what seems close to a real world perspective (to you) from the cockpit, and just move the seat back if the tach is blocked. Drivers who don't use the cockpit view probably feel more at ease with a wide-angle FOV.
With the cockpit view and a realistic FOV, there is always the drawback of not being able to see both sidemirrors without looking to the right, anyway, but the alternative is a "fisheye" perspective. I use my 5.1 audio system to tell if someone's close beside me, and I don't often look there except for a flash view going into or out of corners to avoid running over anyone.
If we were AI we wouldn't have to worry about such things - just mash the throttle and stick to the racing line no matter what.
