Regrettably but also inexcusably, fleeing the scene of an accident if you were driving drunk is arguably a rational choice given current events and real-world outcomes.  I'm absolutely a believer in the old saying that "flight equals guilt" but look at what actually happens if you do:

(1) There is a remote chance you'll escape scot-free and never be held to account.

(2) If you are later caught, then due to the time elapsed, it may be impossible to prove you were driving over the Hawaii 0.08% BAC limit (for those age 21 and up).

(3) Charges of fleeing the scene of an accident or failure to render aid often don't survive the legal process and are frequently bargained away in plea deals.

Running away from an accident you caused is reprehensible but not all alcohol abusers and bad drivers are dummies.  Some of them read the paper and watch the local news too.
