Disagree. Motor impairment is one issue, yes, but so is mental impairment. People under the influence of drugs can have poor decision making, even if their motor skills are fine. Driving on meth is still driving under the influence, and those people would generally not have any trouble with a roadside gymnastics demonstration.
Roadside DUI test is a general test for motor impairment. BAC tests are a nice proxy for that in the case of alcohol, and a legally convenient one as they are precise and objective, but the police care (morally speaking) about your motor impairment not your BAC.
tl;dr, we can already answer the question "is this person too stoned to drive?", roadside DUI test.
