To test the theory, I let my racer sit at a spot for a while, and then came back and finished up the race. Generally, even in the races with twelve racers, the loser is only about a minute behind the winner. Whenever a player passes you, that racer will taunt you, and if you remember you can taunt the racers as you pass them. I haven't been able to figure out if the taunts affect the computer-controlled players, or just your ego. However, I have information on it.
Racer requires that a CD be in the drive of each player in a multiplayer game.
This means you must buy a separate copy of Racer for each player participating in the game. However, since you can only play over a LAN, it is probable that the other players are in the same room or just down the hall, or something. Sit back and watch the scenery - or not. Racer has nice graphics. Don't spend too much time looking at it though, I did and crashed into a wall.
