The hard part is that it often seems like you "have" to drive at times. I'm a single guy living alone, so when my fridge is empty, I "have" to get food. Even when tired or sick. Sure I could use public transportation, but when you're that tired, is it even available? Or would you have the energy to use it? Anyway, that's part of why people still drive while tired. They have to do something important, not necessarily work. So it would be hard to make it publicly unacceptable.
