They're mainly restricted by the regulations now anyway.
Not sure how much we can really use in modern road cars from this generation. The engines are pretty much the same and the ground effect isn't anything new at all.
Certainly enough of a wealth/staff advantage compared to the majority of teams. Clearly their budgets were high enough that they could afford to be disposable in many ways.
They have their own wind tunnels where as most other teams dont etc. That all needed regulating to stop it being a 1/2 horse race every year.
The field spread was always going to happen with new regulations, but i'd say they've all actually done a pretty decent job. It's the closest we've seen in many years.
Yes unfortunately 2 of them seem to have done a better job than most, but from Red bull and Ferrari backwards you can't say who will be the next fastest team yet.
Mclaren might ace it, Mercedes might get their act together, Alpine look pretty tasty on certain tracks. Even Albon is getting into the points quite regularly. It's unpredictable which is great.
Next year teams will be even closer to the front, by 2024 we could have all teams fighting for race wins which would be awesome IMO.
