To be clear, I am not trying to minimize or justify drunk driving. I am just saying that some people at some time may be "under the influence" when given a breathalyzer, blood or piss test, but be in adequate control of their faculties. I think a field sobriety test is a better judge and a fairer way to determine whether someone should be driving. There are elderly who may not be able to pass a field sobriety test, they should not be permitted to drive, regardless of whether they have ingested anything.
It gets worse when looking at a drug such as marijuana. It stays in your system for weeks. There is no blood test, or any test, other than a field sobriety test, to accurately indicated the intoxication level at that time.
