How do I do a hot lapping session with just myself?

I went to session settings, and only check marked practice session.
Left click on session settings, "Remove all" opponents, set "Private Practice" to on.

I select race, then it says, no opponents selected...?

on the far left you have 9 ai selected as opponents. The sim is trying to remind you to add opponents so it can provide 9 cars. So zero that out and you should be able to practice.

 

If you have private practice to on, you should be alone on track no matter how many opponents are set.

 

Correct Steve but nurogize hadn't selected the actual opponents to be the 9 AI cars.

 

sorry, in my roundabout way I was just suggesting that he could have as many opponents as he wanted, so no need to remove them.

 

No need to apologise Steve because you Dave and I are correct but poor nurogize might look like this .
