The bonk! sound and the “close the gap” indicator is too intrusive, and it is not relevant. but don’t get me wrong drafting is the most important.
Imagine one indicator that shows me when I am drafting and when I am out of the draft.
I like to know if I am on a draft because the effect can be very easily confused with a change in slope.
Imagine something like this.
I have changed also the front center panel for more relevant things
this would be your new front top panel
