Please let us turn off that super fast rival in single player

There is always this one fast rival in every race, that is always much faster than the rest of the field. I want to turn off this annoying feature. I want them all to be equaliy good. This way the difficulty slider is more accurate. It’s like that rival is at difficulty 6 or something if i set it to 4. And that is only annoying.

Why even put such useless features into the game? If you do something like that ALWAYS make it 100% OPTIONAL!
