I have just found these three camera modes - the 'Controls' translations just say what is active in that highlighted button/stick (not what the drop downs for that button contain)...anyway.
All these can be used in replays as well.
1, RIGHT CAMERA VIEW (Digital): Highlight a suitable button and select the 3rd option from the bottom - all views
2, LEFT CAMERA VIEW (Digital): Same as above but select 4th option (notice the characters look the same though?) - all views
3, DRIVER LOOK LEFT/RIGHT VIEW (Analogue): Highlight a suitable stick function and select the 2nd option from the bottom (notice it auto assigns the opposite throw of the stick) - only for 'Bumper' and 'Inside' views.
Well thats a bit more worked out!!
