I`m single (and will be) screener .. so for me there is always compromise between corect FOV and loose of pheripheral vision+sense of speed .. correct proportions, curve shapes, elevations, distances are more important for me .. years ago it took me only few laps to settle with correct FOV and since than I can`t drive any other way .. so 23" screen, 33 FOV and i`m happy panda .. my situational awardness is not suffering or at least not causing any problems and most sims have reasonable sense of speed I get used to ...
Driving in bonet view (in sims with crazy high FOV on it (AC) ) is not usable for me, but it is not sin to use it, sin is that FOV setup for every camera (or at least unified cockpit and bonet view) is not standard feature in every sim ..
