It’s because of the spray these ground effect cars produce from the diffuser. Very hard to get around seeing as that aero function is the whole reason for this rules framework. FIA is just not going to green flag any race under conditions that demand Full Wets when the visibility is as poor as it is. Makes sense then to scrap that tire. I’m all aboard on this, it’s perfectly logical given the circumstances.
I would - of course - prefer to have proper wet races again, but that won’t happen until 2026 at the earliest, I would assume.
The current era cars use ground effect to produce most of their downforce. This air that flows through the underbody is then thrown almost vertically up in the air when it leaves the diffuser. The idea behind this rules framework is that this will get the dirty air out of the way (by tossing it way above the cars) so that following closely is easier. Previous-era cars left a huge wake of dirty air behind them which made following for extended periods of time impossible.
The side effect of throwing the dirty air high up after it leaves the diffuser is that the same thing happens with water when the track is wet, since it also gets sucked into the underbody. That’s why you see these cars produce “rooster tail” spray when running in the wet. This type of spray hampers visibility enormously and is currently the biggest obstacle in the way of proper wet running.
2026 will bring the next major change in the rules framework, so there is a chance cars designed under those rules won’t produce the same sort of spray, if they decide to for example move away from ground effect.

I understand some of this.
Are you saying the diffusers make wet racing impossible because of visibility?
What happens in 2026?

Just introduce mud flaps
