Never heard of that before, but I will not hesitate to quote it if
I encounter a Police roadblock while driving home from this year's
New Years party.

It won't work if they find you over the legal limit of 0.08. The body
doesn't produce enough alcohol to get you up that high, and the test
equipment will easily catch you.

The problem comes when the government tries to reduce the amount to a
lower level, such as below 0.05, since there are no reliable tests to
indicate whether a person has been consuming too much alcohol, or it is
the natural state of a person's chemistry. However, in these countries,
it is also very easy to get above their legal limit with very little
alcohol consumption, since any amount adds to the percentage already in
the blood.
