[SCRIPT] Script Error

[Amnesiaplayer]

Looking away from your script, and just at what you said I'd presume what you want is

void Info(string &in asEntity)
{
SetMessage("Message","CarScript", 0);
}

Then put this in void OnStart()

SetEntityPlayerInteractCallback(NameOfEntity, "Info", false);

You don't need the setentityplayerinteractcallback, this is possible in the entity tab itself, for the entities. right?
