Before revision:  Initially decreased task performance and increased steering effort , and partial reversal of these effects with prolonged task exposure . Unexpectedly, the model also reproduced another empirical finding: A local optimum for motion down-scaling, where path-tracking is better than with one-to-one motion cues  .
