The concept of what gets called "evaporation" is really anti-intuitive for a lot of people I think. Maybe there should be a better term for it because it makes it sound like a sort of magical process. But all it is, is the idea that in areas with a lot of demand for road space, that space will tend to fill up to reach a certain level of congestion. And that level of congestion is determined by what drivers will tolerate before switching to other modes - it's not determined by overall road network capacity.
