When you drive a cab where the throttle and/or Brake handles is out of view you don't have a good sense of in what position your handle is. This could be so easily fixed by adding vertical rows of minimal dots to the hud. I noticed when starting TSW5 it was way easier to understand what you are doing out of view in the normal hud. On the Pendolino I don't see what I'm doing in minimal HUD but on the Metrolink it's pretty obvious what is happening as the handle is right in front of me
