Your propositions are interesting.

They will never "go" in the US, however.

In the US, we tend to legislate to control things with a "stick" rather than a "carrot." Legislation has to be aimed at punishing people for it to be considered "good." We would rather see an entire generation in jail than actually "fix" the problem.

We, as a society, are not - at all - interested in reducing deaths by intoxicated drivers, unless it involves punishing someone. Anything less is considered pandering to the perceived "criminals." Therefore, non-punitive solutions just don't interest us...
