Take a look at VTOL VR: every button can be pressed IN VR! Every switch is active, etc. The best VR simulation ever and no external button box! Too bad it's a plane and not a car! But some big titles will get it someday...I hope.
I've tried that and it's great for a preflight before you are actually flying the plane, but not having any tactile response is a serious liability at other times.
The bottom line is that it prevents you from reaching out to a control by feel and using a control without taking your eyes off the road or somewhere else.
When you know where the controls are having a real button switch, knob, toggle is much more satisfying.
There are also controls that are not represented in a cockpit.
In Dirt Rally I use a joystick for the arrow keys and have an Enter, Cancel, Esc button mapped that don't exist in a cockpit.
In all driving titles I use a joystick to move the seat fore/aft, up/down and also have a tilt toggle for titles that support those. You can argue that once you have a car dialed in that this is no longer important, but it is something you have to do with every new car you use in most titles and if someone else uses your rig who is a different height than you are.
