A proposed campaign to eliminate car crashes due to alcohol threatens to be repressive and impractical.

I don't have any data, but I would guess that most of the time when people drive dangerously drunk, it is not due to the precise details of the current laws, but rather due to people who don't make any attempt to follow them. Thus, changes such as setting a lower legal limit will not work unless they terrify people. Besides which, you'd need to carry your own breath tester to follow such a law carefully.

Some of the proposals are harmless and might be useful. For instance, to regulate marketing of alcohol more carefully — if that will help, by all means do it. Preventing sales to people who are drunk is legitimate, but it is easier said than done.

A simple game can test for the mental and physical acuity necessary to drive safely. Putting one in the car would make it possible to detect when the driver is too impaired to drive safely, regardless of the cause. When your reflexes are marginal, the law could say you can drive to a place where you can safely rest for a while, but only with your emergency blinkers on — or whatever rules would promote safety for that shorter trip.
