And unless unless you have serious brain damage, weight issues, mobility issues, or are really
old, you would do fine on the "roadside gymnastics."
If you could explain your level of understanding of the tests (without google) then I will have a better idea is how else to proceed in explaining them, but as of know, it reads like a great add for a DWI attorney. The SFST isn't some collection of coordinated complex moves - they are a scientifically based and proven simple system for dividing attention between physical and mental actions, similar to the behavior driving a car. If the SFST battery was anything less, it would not be the widespread and widely accepted system that it is.

SFSTs have several components in them that make the tests fairly conclusive as to a person being impaired.
That said, a good example is my brother who has Multiple Sclerosis (MS). His condition will affect 2 of the 3 tests. However, the HGN should not be impacted by his MS. Either add or take away other contributing factors like smell of alcohol, bloodshot eyes, slurred speech and the initial suspicion of why the person was stopped (weaving, crossing center line, etc) can bring the officer to the point of probable cause to arrest and take them for breathalyser or blood draw with a warrant.
