For example, Audi R8 LMS Ultra @ COTA. So if you happen to select that combo, its data simply doesn't exist. I don't think the real reason for no practice mode has been mentioned here yet, but this is a very good example of what the challenge behind making it work properly would be.

I used to think that they could convert the Party Play mode to be a Sandbox mode, but I wasn't factoring into it the fact that there are simulations for car and track combinations that are performed, and tuned behind the scenes that make the bots work.
