While I don't want to take an unfunny joke I made in the Hacker News comments too far and am sorry for hurting any British people's feelings, "drunk driving" does make sense as a literal description of an act, unlike "drink driving". "Drunk" is an adjective which modifies "driving" (which is used as a noun in this case).
