For those of us who love to drive, having to take time off because of work, life obligations, or necessary automotive repairs and maintenance is no fun. We inevitably spend the weeks or months in which our cars are parked dreaming about getting back to performance driving at our favorite tracks. Thoughts of driving inevitably lead us to wonder whether our driving skills will have diminished after time away from driving at speed. Will my shifting be as smooth? Will I be able to brake as late as I did on that last session months ago? Will my lap times be the same as they were when I left off?
