This is already a known bug, and is already on the list of things to be fixed.
F1® 23 - Community-Raised Issues (& EA Racenet Updates) - Answer HQ
its because of volumetric fog there is currently no way to disable it on PS5 its only fixable on PC by disabling it in the hardwaresettings file unfortunately I have no clue how this failed to get noticed or fixed before the games launch its like they didnt test the game at all
Edit for those on PC that want to disable it:
1: Set all graphics options to what you want depending on performance (including Lighting as high as you want, which is what the fog falls under).
2: Open hardware_settings_config_vr.xml under Documents/My Games/F1 23/hardwaresettings (Save a backup!)
3: Find the following line and change volumetricFog to "false" example: <lighting quality="3" volumetricFog="false" volumetricFogMapWidth="1920" volumetricFogMapHeight="1080" />
also a note if you do this then change lighting settings it will auto re-enable fog so you have to go disable it again
