I agree. All I care about, as a racer, is my laps, fuel level, and tire wear. I'll check my lap times at the END of a race, not during it. This information may be more useful for practice, but if I'm taking my eyes off my car long enough to read a number of several digits, I'm likely in the pit lane or something anyway, and can use more focus to do so.
We haven't had any problems knowing which dashboard to look at, but we definitely would not use sort dashboard by place, because that would just mess things up. There's already a color coded racing order on the side to look at.
