>>That means that in many cases, a good-but-legally-drunk driver will be vastly out-performing a terrible-but-sober driver.
Not really. Drunk-driving is illegal due to increased reaction times, not decreased driving ability. You can be drunk and properly follow the traffic laws, but if you run into a situation that requires quick reflexes you're much more likely to not react quickly enough.
Whereas terrible drivers are generally terrible in other ways.
Someone who has a low reaction time overall might have a better reaction time drunk than someone with a reaction time of a dead cow. My friend claims 0.1 reaction time on a game where you have to click your mouse (I believe him because he's a professional gamer so it makes sense), while I score 0.2 at best (which is average) and older people score worse and worse
Hence why some people are fighting the politically unpopular fight to get older people off the road. No one wants to be seen as the one that "stole grandma's freedom".
