I was standing in line at Staples this weekend and looking at a display of personal alcohol testers.
As the name indicates, this little machine records the blood alcohol level of the user so he or she will know if it is safe to drive.
In theory, this sounds logical, but in practice, not so much. Does a person who is drunk have the presence of mind to blow into a personal alcohol tester, and if so, would he or she also be sensible enough to follow its directive and stay off the road?
My guess is no. People who have that kind of self-control either do not drink to excess or have made other arrangements — designated drivers or hiding the keys — before choosing to drink.
