As long as we still have ground effect cars I sadly don’t see another outcome. The entire point of the regulations was having diffusers that throw the dirty air vertically behind the car, which in theory reduces the amount of turbulence on ground level (which would make following easier). And we saw this working at the start of 2022.

Sadly, this also creates the huge rooster tails of water when the track is wet, and it’s sort of unavoidable. The only options, then, are either red flagging or re-evaluating the level of acceptable risk. And there is just no way F1 are going to do the latter in this day and age.
