These points are probably on a to do list of a Kunos dev somewhere but surely wont make it into code anytime soon considering the current bug fixing and finalizing 2019 content priorities.
As a workaround, make sure to map the F2 keyboard key to a button on your steering wheel to be able to switch the entire HUD on/off mid race (only do so when safe on a long straight as one hud screen will completely obstruct your view when cycling through the screens).
screen 0 (blank) and
screen 1 (racing hud)
is what you want.
