Actually, that's not even really a solved problem yet, but
that's not well-known outside of people who litigate
drunk driving cases for a living.
I'm not surprised - I found the assertion that the tester
could tell the difference between drivers and passengers
and open or closed windows and precise enough alcohol levels
reliably enough to call the police without major false positives
and false negatives to be somewhat dubious.
In particular, testing for Ethanol as opposed to metabolites
sounds highly unreliable, unless you're really just testing
for zero or non-zero quantities of the stuff.
