> PS - I suspect, but cannot show data, that existing upcoming safety technology may decrease DUI caused fatalities in particular "driverless" automations like lane centering, automatic lane-changes, and autonomous navigation. While I don't consider this technology mature, it may still be safer than an inebriated driver.

While current self-driving technology is obviously unsafe when given total control, I think it could be turned into an extraordinarily effective safety system: program it to only take accident avoidance measures and low-level corrections like lane centering, and crank up the thresholds so it only gets invoked in clearly dangerous scenarios.
