Interestingly, SafeKey Corporation has found that, through the use of the SafeKey, people become more aware of their own state of mind, partly because their impairment, if significant, prevents their vehicle from starting. Needless to say, even short periods of loss of mobility, are unpleasant occurrences – even if they save lives, limbs and property. This result is a fortunate, unintended consequence of the product.
Consequently, we categorize the SafeKey System as a prevention device – it deters persons who are impaired from driving in the first place – until they are suitably unimpaired. In a real sense it is not only an “early warning system” that just costs a few hundred dollars, but it’s also a true interlock device that deters DUI before arrest and/or crash.
