Here is a screenshot 1 1/2 hours before the race, with the check list showing my drivers are healthy to race. Note, I haven't forgotten that the check list checks to see if my drivers will have a decent amount of health when the race begins and not for the current moment.
I think this is peculiar behavior and goes against what the check list is supposed to do: Checking to see if my drivers will have a decent amount of health when the race begins, rather than my former misconception of it deeming my drivers healthy at the current moment.
