Found another occurrence of this type of artifact, this time it isn't during a night race, but during Silverstone, rainy conditions and while driving an F1 car.
So the issue seem to be larger than I initially thought. and might be tied to the camera "TV Pod Offset", perhaps it is particle effects or motion blur being calculated at an erroneous angle?
I have only been able to narrow it down partially, this seem to only happen when TV Pod Offset camera being used and not other camera angles.
Edit: I have now been able to narrow further, it only occurs when particle effects are enabled (low, medium or high), and when using the TV Pod Offset camera.
Edit2: Captured the differences between particles on vs off during wet races.

I noticed it too on PS5
