I totally expect it. Wind tunnels can validate the model for a single
car, but what everyone really wants to know (as of ~ 8 years ago) is
what happens with two cars, which is much closer to the real
environment in a F1 race.

And doing two half-scale cars in a wind tunnel, that's going to be a
huge wind tunnel... not affordable for any F1 team's budget. For
boundary condition reasons, it's going to have to be more than 2X the
width of a one-car tunnel. Ouch.
