Highway not smooth when exceeding 100 fps on PC

I found several old posts in the subreddit talking about this bug. The highway stops looking smooth if the game exceeds 100 fps on pc. I thought it wasn't true but i lowered the fps to 100 and it looks very smooth and even feels better than the 144+ fps i usually get. It does not have anything to do with vsync or things like that, so it's a bug I think.
