The problem with aquaplaning has the potential to become much worse for 2022 for two reasons:
1 Same tire surface, but less downforce means aquaplaning more likely.
2 Downforce from the bottom of the car obviously has much more chance to be disrupted by standing water than downforce from the top of the car.
For the latter problem Gary Anderson has suggested a larger increase in tyre diameter for the rain tires, but with the already huge diameter proposed for 2022, the visibility problem would only get worse. One more reason to stick with smaller diameters for the dry tires.
