I think what we'll find s that there will be different approaches for different locations, occupations, and so on. Electric may be pat of a solution for city dwellers, but my guess would be that much of it won't be privately owned.
I think what we would see ideally in cities is most people living in walking distance to work and amenities, a certain amount of mass transit, supplemented with different types of electric for people who are working in mobile occupations within city and to hire for others as needed and for trips out of the city.
The important point though being that not only would many of the vehicles be electric - there would be fewer of them, buy a long way. That accounts for quite a few people. We could also see reduction of large transport vehicles into cities and better use of trains.
Rural areas would be a different story and might require different solutions, but fewer gas vehicles does not have to be the death of rural areas.
While it should be obvious, it seems like it isn't - the age of the private car has overall been bad for rural areas and villages. In many cases they have emptied out as people are pulled in by the gravity of cities, not only for jobs but services and entertainment. Two generations ago many of these places were more self-sufficient, has more services, and better public transport links to nearby larger towns and cities and also to outlying areas.
