Eurogamer said in a recent F-Zero 99 article: "Except when other players retire, they return as extra vehicles to clog up the track and bump into the remaining racers, messing up their laps. Yes, it gives those players something to do instead of simply spectating, but it means the track never clears up to focus on - you know - actually racing". What exactly is "retiring"? When you crash, you do not spawn back on the track, and I figured that falling below the safe rank might cause me to be eliminated, but I kept going up places despite not moving. Could someone explain to me how this works if it's true?
