I have another little question. As i understand only 4 out of 6 drivers of the team can take part in the race (is it a tracker limitation). My question is: what if driver 1,2,3,4 do their 1st stints and then lets say driver 1 won't be able to do any more stints in some reason (i don't know... PC crashed, dog died etc) is it possible then for driver 5 to finish the last 3 stints of driver 1 or the remaining 3 main drivers will have to finish race without help from reserve driver and do more stints?
