In the countryside where I am there are 2 buses a day (only during the school year, for students, although they let non students ride it) and the nearest train station is 30 minutes away.
The real concern here is people driving when they shouldn't (drunk, tired, etc.) because they have no other option, putting lives at risk, so to the degree that self-driving cars will curb that I am wholly for the technology.
You should volunteer your countryside town to be the guinea pig place for them then.
