The process is simple. Send out one car at a time, and write down the laptimes, use their best one. And when it comes to race time, each driver is called in order to join the starting grid.
After the next week or two, could the races be moved to Saturdays or Sundays? Some of us still have to go to school, and where I live, after next week if the races continued on Mondays at 18:15 (1:30 pm here) me and possibly several other drivers would be out for the rest of the season. Also, weekend races are usually more friendly to the drivers
at the moment i don't see a way to make the events on weekends. i was thinking about the weekend for the 360 event (last race). but all other events are on monday, as posed before the season started. sorry.
