Why the computer in local game can play only main cars(speeder, sprinner, antislider,easyslider,and slider)?????

[Edit by Mike Nike: i allowed me to change the topic from "Why?" to "Why the computer in local game can play only main cars?", since "Why?" is just a little bit too 'not-saying-anything']

please read the readme files
if you have other cars on your computer they are probably in folder /cars/tmp and to play with them u have to move them from there to /cars

I guess you mean with "the computer", the computer opponents (made by Artificial Intelligence). Since the A.I. is defined by a set of selfcreated lines and some other settings, the first thing you would have to do is, to create your own A.I. files/lines ... with the cars you want (and at the tracks you want).

But i think it might be better, if you read the documentation.
For this, have a look in maybe each file in your language in your Turbo Sliders\doc folder, example: "C:\Program Files\JollyGoodGames\Turbo Sliders\doc".
