Purely scientific inquiry - please don't read any ulterior motive here:
Is there any research showing the practical effects of, say, relatively low level of intoxication on flying skills, versus effect on driving skills? Put another way, what reaction time is essential for competent piloting, versus competent driving?
Aviation has rightly called for "zero tolerance" in this matter, but various jurisdictions have different limits for drivers. I'm interested in whether this makes practical sense.
