Thank you for participating. Figured out how it works by now.

My first AI Race in the Demo with AI Setting As.

Thank you. I will try it.
In multiplayer, I was shown the option in the box at the bottom right. Not in single player.

Welcome Tobias

Thank you Phil!

Hi there.
My name is Tobias, 46 years old. I'm new here at LFS, but not in simracing.

Hello everybody.
I downloaded the demo today and drove a few laps in single player and multiplayer mode.
Now I wonder how I can switch between the 3 cars in single player mode. In multiplayer this is possible without any problems.
Did I miss something?
Thank you in advance.
