Not untrue, but such an idea would run completely counter to F1's values and principles, which have long been founded on excellence, competition and meritocracy. It would make all design ideas and IP public, rather than private, property and transform the sport into an "equalitarian" (equal-outcome) system.IF the teams had to submit a fully detailed mechanical model of the car as it sits in parc-ferme, the teams could converge more quickly, and not be inclined to spend so much.
I'd be very disappointed as an engineer working in F1 knowing that any great idea I had would be immediately known and copied by all and sundry and hence rendered close to useless, and my incentive to innovate would be significantly reduced.
