Wiper position changed with rain effect. Major wiper is just move left to right and reverse.
But center wiper needs different wipe motion. it moves center to left and reverse, center to right and reverse.
Just T10 couldn’t make another wiper motion system for a few car. Not for wide cockpit view.
This is the most logical reason as to why the wiper position changed
It changed the same time rain was introduced for Horizon 2 and FM6, all wipers on the cars have to carry the same motion and they most likely didn’t want to create a whole new wiper motion just for the Koenigsegg, which would probably require more work than most people think
Is the position of the wiper really that big a thing? Sure I’d like to have it in the middle for it to be more authentic but this should be the least of both turn 10’s and our concerns with the game.
