In principal I agree with your point, but I’m sceptical, it will work the way we wish, since there are more things connected to that, when it comes to car design and setup.
First off: The 2023 cars cause more dirty air than the 2022 runners. And I do remember a few races at the beginning of 2023 where this was clearly visible. The FIA tried adding more DRS zones to remedy this, but it’s way imbalanced. At some places it doesn’t make any difference, in others it’s just “Push to Pass”, which as a motorsports fan is frustrating.
But it must be even more frustrating for the teams. The designs and setups for their cars are always trade-offs and since DRS is part of the formula, it is part of the trade-off (Look at what McLaren was trying to do in Spa, or back in F-Duct days in Monza). Before I write a whole essay on it, let me showcase one of the dependencies: Powertrains and gearboxes are fixed until 2025. If you’d get rid of DRS in say 2024, those who made the trade-off to favor traction over high-speed will suffer and will only be able to pass if they sacrifice their Aero downforce. Or they’ll keep their grip levels and just not be able to pass on track without a huge tire delta. In other words: DRS gives the designers one more degree of freedom to arrive at their concept. Without it, I fear that car concepts will merge even more, than they do now, giving aero even more of a weight and due to even less difference, racing itself might suffer. This is only one example and holds true even when changing it at the same time as the drivetrain. So it’s a pretty delicate thing to balance, when taking away just one aspect.
It has to be noted, that the car was initially built for a competition named “Formula Student”, where there are several disciplines and the tracks are very narrow and twisty. The team added these fans to the 2019 runner to increase grip (double from what I understand) and maximize traction especially at standstill for this record (As you said, not to prevent taking-off). And since the wings would take up too much drag, they only left the undertray with the fans in terms of aerodynamics. Aside from that it is an electric car with four powerful yet small motors, placed at the wheels. Congratz to the team and AMZRacing!
