alcohol impariment (was Kerbside Motors is no more)

[Dave Eaton]

this (or any blood-related measurement) is also not a reliable measure of
impairment - which is supposed to be the actual point of the law in the 1st

enforce.

a much more effective measure, by the way, is the "walk the line" test so
beloved of movies and southern states...

the presence of cells, etc. that estimate is reasonably close.  So - you
make a guess and say, in effect, "That's close enough for state work."
