The aggressive nature of the Zoan Devil Fruit may be a factor that prevents Kaido from staying calm and using Future Sight (FS) constantly. As a result, Kaido resorts to his drunken states, in which he exhibits a calm personality and can utilize Future Sight.
Furthermore, Kaido had no reason to use Future Sight on the rooftop when everything used against him did not force him to do so.
However I don't think that has anything to do with it, it's just Oda saying, man use it when you really need it and that's it, just like Luffy's FS is flawed most of the time until the decisive battle.
