@BillRM,
Absolutely nothing you are saying addresses the problem of drunk driving--nothing.
Let me repeat what I said to you before...
It seems important to you that people, including yourself, be able to drive drunk. You decry past decreases in the legal BAC level, and you want it raised again, beyond .08, so more people could be legally driving in an even more impaired state than current law permits. You think drunk driving is no worse than driving while extremely tired or very emotionally upset, ignoring the fact that people shouldn't drive in those states either if they impair judgment or concentration, or reaction time, or any of the abilities required for responsible driving.
Why it is important to you to be able to drive drunk, and beyond the current legal limit of .08, is anyone's guess. Drinking is obviously important to you, despite your many attempts to deny that, because you are arguing against attempts to restrict drinking on the part of those who drive cars. You've even voiced your concerns about lost revenues to bars and restaurants if people have to watch their drinking before they get into a car. You want the legal limit raised to that which is most often found in deadly crashes, something that would make it acceptable for people to consume even more alcohol than they do now before they get behind the wheel, and increase the probability that even more deadly crashes, as well as more crashes that result in non-fatal injuries, would occur. Why is it so important to you that people be allowed to drive drunk--very drunk--and way beyond the .08 limit where impairments can already be clearly demonstrated? Is foregoing binge drinking before driving that big a hardship for you?
If Thom Swift hadn't been drunk when he got behind the wheel of his car that night, he wouldn't have to worry about the length of a possible sentence, and you wouldn't have to worry about the cost of incarcerating him, and Barry Lancaster would likely still be alive. The problem is drinking and driving.
If drinking is so important to you, go right ahead and drink, but don't get behind the wheel of your car after you do that. But, if you do choose to drink and drive, and you kill someone, don't whine about the length of your sentence, or your "usefulness to society" or how much it will cost to keep you behind bars, or any of the other crap you keep coming up with--none of those things will obliterate your responsibility for taking a human life, which is why they are all very much beside the point. Cars are lethal weapons and they have to be operated responsibly, by responsible drivers, and when drivers fail to act responsibly, the law will hold them responsible for their actions.
