The solution for transport is electric trains and very lightweight electric vehicles, like electric bikes and other 4 wheel things lighter than 400kg. All powered by nuclear energy. I even foresee a network of narrow rail tracks for cities, supplied by a collection of warehouses for freight for the last kilometer to supermarkets and shops. Such rail is much easier to build on existing infrastructure.
