Patiently waiting.
OK, you say prohibition. It's been tried and people still drank, still got in accidents involving alchohol.
The Libertarians, according to you, say that no law should be involved, they should be able to drink and drive.
My common sense tells me that if you drink alchohol your reflexes are impaired. We will not get people to stop drinking alchohol. If you drink alchohol you should have a designated driver that does NOT drink alchohol.
Common sense.
