That's where the F1 and Scaled sit. F1 teams routinely do a lot of wind tunnel tests (which negates the point of the OP - they are definitely not replacing WT by CFD)
I didn't miss it, I was just adding a comment that I thought might help.
The F1 boys certainly do run big wind tunnels full-time but only to test models that have extensive testing through CFD. It only takes a short amount of time to change a model with CFD, it takes a lot longer to build a perfect scale model then run multiple tests in a real tunnel.
Both are needed, the CFD cuts down the overall time, effort, and cost by quite a lot.
