Working on a case involving an out of control race car travelling up a steep bank, I came to realize that the familiar AASHTO formula for braking distance is an approximation that introduces significant error when applied to steeper slopes. I am sure the originators of this formula were well aware of its shortcomings, and I do not intend to be critical of their efforts. But I think those who use it should be aware of its limitations, particularly forensic engineers who could get blind-sided.
