A person who didn't learn from the first DUI is either an idiot or an

he's a borderline alcoholic who is likely to drink and drive (or fly)

enough to get drunk regularly.

Exactly. One DUI is strong evidence of alcoholism; two DUIs is virtually
proof of it. So the question is whether or not this person still drinks. If
he still drinks at all, he needs to stay on the ground.
