Efficient transit goes hand in hand with density. Stupidly simple example: Let' imagine we had a network of autonomous Teslas that drive everyone at 200mph for $0.05. We'd still end up putting two people in each Tesla, because it would double the efficiency. If you want to be alone, cities are not for you. Transit in cities will never be both efficient and solitary. The whole point is that there are a lot of people going to a smallish set of general destinations and we're better off bringing them there together.
