The sole reason the road problem is known is because when we build new highways going to the city centre, we start using the roads for less important things, thus reducing the efficiency of using roads. It's a well-known problem in city planning. E.g. Instead of only using a car when you need to get there "now", you start using a car to get some coffee in the central area. So there is no difference and that's why I mentioned it.
