I've been looking around on the LFS Manual and here on the forum, and didn't find alot about it ...
It probably seems extremely obvious to most of you, but all the same ...

Is the following correct ?

In Demo, you can have 15 guests maximum, 12 racers + 3 spectators.
In S1 and S2, you can have 47 guests maximum, 32 racers + 15 spectators.

This is actually 16 (Demo) and 48 (S1 and S2) connections, including the host connection ... ?

Each track is limited in the number of players that can drive on the track at the same time.
Even if S1 and S2 modes allow 32 racers to drive, not all tracks allow so many ...

Here is a list of the possible number of racers driving on the tracks :

Single Player (SP) numbers are from in-game (The player + AI cars).
Multi Player (MP) numbers are from around the forum or just guessed.

There is no point in setting a server to 47 guests if only 16 people can actually drive ...
So can somebody please check my list and correct any errors ... thanks ...

I think that they're all right - apart from 8 lane drag. Surely only 8 people racing?

Maybe not?

I don't know, that's why I'm asking, lol ...

Only 8 people can race, but can more be "on track" when a race is not going on?
And if that's the case, surely it'll be the same for the smaller Drag Strip?

Does anybody else know?

Has anything changed here since the last patch ?

AI can't drive in these tracks. So 1 car in SP for the 3.

You can have 32 cars on sp, with a lil trick arox posted in the bugs forum.
