Captain wrote as a somewhat irrational response
Captain, no, but I also have not agreed to drive WITH the impaired driver who is about to hit me.
In the particular case, I am relying on my buddy to be up front and honest about his abilities as we go 1200+ feet from "The Big Air Tank." There is no comparable relationship between me as a driver on the road and every other driver.
Want to try again why your buddy shouldn't be honest with you about potential problems?
Just hand your insta-buddy a medical form to fill out before the dive if it is that important to you to know his medical history. Don't dive first and complain later when you find out he has a medical condition that you think he should have disclosed to you, that or else don't dive with insta-buddies.
