the case for .05 BAC is thus very weak
That's because you don't value saving human lives, or reducing the number of alcohol-related auto accidents and the injuries and property damage they cause. Your main priority seems to be drinking, and drinking without wanting to be bothered by having to arrange alternate transportation in the event your drinking goes over the legal driving limit.
That's no reasoned or rational argument against lowering the legal limit to .05. It's simply an ego-centric statement of your own selfish preferences and your own lack of interest in either responsible driving, or making the roads safer for everyone.
Don't think you've won an argument you haven't even participated in. Your self-centered, and adolescent whining, about intrusions on what see as the "good life" of drinking and driving--and your outrageous, and adolescent, sense of entitlement, about how you should be allowed to abuse the privilege
of driving, by being able to do so, even when impaired--do not constitute participation in meaningful discussion of the topic, let alone winning any sort of argument.
The case for a .05 legal BAC level isn't weak at all. Eventually, I think that we will institute that level. At the moment, all it is is a recommendation from the NTSB, and a very very recent recommendation to boot. Give it time.
And, when DrewDad said this about you...
I think it's tacit agreement that you're just kind of a douche, and there's no point in trying to have a rational conversation with you.
he hit the nail on the head.
