Sweet...here's the skinny----pick 5 drivers each week as starters plus 1 more as your garage driver....you can use a driver 10 times in the 1st 26 races (the regular season)--after 26 races, your driver used counter resets and you get 5 more uses for the 10 race playoffs...
you can choose to use your garage driver-or not.....if you decide to use him, you have until the green flag of the final segment to put him in and swap a starter out who would go into your garage---useful for an early crash
at the end of the race, only the 5 drivers who end up in your 5 starting positions are scored and are counted as used...
there are also 4 head-to-head matchups each week---pick which driver finishes ahead of the other--they are worth 10 points each...
the system will display how many times you've used your drivers....
