... ah but there's the vice versa of that of course. I.e. should a sober driver just happen to crash into another driver, where the latter just happens to be at 81 mg ( when the legal limit is 80 mg ), and both get killed.... then whose fault is that and / or would this be but down as a D&D fatality statistic ?
Now, so that we can assess the true enormity of this problem, would somebody be so kind as to remind us all of how many passengers have been killed in commercial airline accidents in, say, the last 10, 20, 50 years or more, as a result of (apparently) inebriated pilots ?
