The benefit of adding capacity is that it adds capacity: more people get to go wherever they want to go within an acceptable travel time (or the same people get to do so more often, or some of each). It should never have been promoted as "solving traffic", in the sense of letting the imagined voter get to use an otherwise empty road while still making everyone else pay for it. That was never reasonable. Overcapacity can happen, when people want to connect distant places even though there's only enough traffic to justify 0.2 roads. People's taxes pay for one road or zero roads, not 0.2 roads. For the few people who happen to use such a road, paid for by everyone's taxes, it's a good deal. But it can't be normal, even though that's how it came to be perceived. We just wouldn't have a road network if the whole thing was only 20% worth building. We do have one, because there are lots of places where it's more than worth the cost of building a road, but only if the road connects to other roads.
Meanwhile, the Katy doesn't live up to its image as a giant parking lot. Traffic there is dramatically slower than free flow for only an hour or so at each commuter peak, and even then it's slower by only about a factor of two. That's about right, given the subsidies we have for ultra-low-density housing.
