ARE THE STANDARDIZED FIELD SOBRIETY TESTS ACCURATE?

The field sobriety exercises are balance oriented exercises or tests. So because each person is different we're not designed to walk in a straight line with one foot in front of the other, which is one of the field sobriety exercises, nor are we by design normally standing on one foot. So because of that reason and everybody has different limitations or flexibility or balance, it is not an accurate test.
