Not sure what to call these, but in ETS2 I was using the eyeX to look around, but instead of centering on what I am looking at, I would love to be able to have it like the steering axis.
The problem is when looking away, the camera then moves way off the road, and it can take multiple seconds to be able to see the road again. I rarely need to look behind me, so having it more like trackir, and be able to define how far to each side it should go, might be more handy.
