// it passes it, the kart reverses and crosses the finishing line
// backwards. Just before crossing the finishing line the kart will be on
// the last lap, but with a distance along the track close to zero.
// Therefore its position will be wrong. If the race position gets updated
// after increasing the number of laps (but before tagging the kart to have
// finished the race) the position will be correct (since the kart now
// has one additional lap it will be ahead of the other karts).
// Without this call the incorrect position for this kart would remain
// (since a kart that has finished the race does not get its position
// changed anymore), potentially resulting in a duplicated race position
// (since the first kart does not have position 1, no other kart can get
// position 1, so one rank will be duplicated).
// Similarly the situation can happen if the distance along track should
// go back to zero before actually crossing the finishing line. While this
// should not happen, it could potentially be caused by floating point
// errors. In this case the call to updateRacePosition will avoid
// duplicated race positions as well.
