Whatever they come up with would have to be easily installable/removable and would have to fit all cars - that could mean fixed mounting points etc, currently the only fully "standard" parts around the wheels are the wheel covers and the brows, i somehow doubt those limited mounting options could take a full wheel arch but some further deflector could be fitted, what they don't want is those having too much of an impact on the aero, surely.
Here's the full text from the media statement:
Wet weather update
Driver feedback has suggested that there has been reduced visibility in extremely wet conditions with this latest generation of cars, which is a key determinant on starting, or needing to suspend sessions.
Therefore, the FIA commenced a study to define a package of parts aiming to suppress the spray generated when running in wet conditions. The study focused on the following:
- Definition of a standard bodywork kit, aiming to suppress the tyre spray from running in wet conditions by use of minimal bodywork over the wheels (wheel arches).
- Understanding the contribution of surface water picked up through the underfloor tunnels to understand its significance.
- Ensuring that the design does not unduly hinder pitstop tyre changes.
- Seeking additional benefits such as additional lights to improve car visibility.
- Devices only to be fitted either before a race or during a red flag due to extreme wet conditions
Preliminary work and an initial concept were presented to the Commission, and the FIA will continue to work to refine the proposals, with further updates anticipated in 2023.
They could come to the conclusion that a large part of the spray comes from the aero and then i wonder whether there's anything they could do about it.
