I strongly suspect the next frontier of driving safety is sleep. We already have inclinations that insufficient sleep produces a mental state analogous to intoxication. However, we don't seem to recognize that someone going home after a 24-hour hospital shift, or an on-call worker who caught a production issue last night, or a new parent, or just one or the majority of adults who don't have healthy sleep patterns, is making a dangerously irresponsible gamble with other people's lives in exactly the same way as someone who downed a couple of beers.
