Yeah, it turns out that in very specific and controlled situations, using a fan to make downforce is great. It's also a very obvious thing to do in those situations and doesn't do much for you otherwise.
Imagine a normal car having to carry around the added weight of fans, COPVs, and the plumbing to make it work. And only being able to use those only if the track is clean and there are no other cars nearby.
You actually raise interesting point. What if we could remove bunch of complicated suspension and replace with a simple fan?
They make those - they are called hovercrafts. They tend to have lots of maintenance issues.
What suspension would you recommend removing? Are you envisioning some ridiculous Flymo-style car? I can attest that a Flymo lawnmower collapses onto the floor when its weight increases (eg with wet grass).
This is like asking to imagine a Hoover vacuum to have those fans. It’s silly because it would never happen. This is not a normal car. Comparing it to a normal car makes no sense.
