I do like Evils idea of doing a test season for GT mod. If it works maybe we would think about some kind of endurance division.
I have been musing on the problem of long GT races. It seems to me that if you set the laps so that it would take (say) 1 hour and five mins to complete, you can then drive for an hour and dive into the pits. Someone else (who started in the pits or drove round to the pits) who has been waiting for an hour drives out and drives for an hour - repeat the process and the last driver drives until the chequered flag. You get a three hour race with three drivers that would have taken 1 hour and five normally.
Theres one problem with that. GPL allow only 19 drivers(+ server) to race online. So with this system we wouldn't have to big grid.
We can simulate drivers change in GPL. We can have 3h races and every team would have 2 drivers. Every 3h race would be divided into two 1.5h races/stints. Afther race/stint 1 second group of drivers will enter server, in the same order at the first stint ended.
If first driver had a DNF, than team would get 1 or 2 laps penalty.
This system worked quite well, when Simracing.cz organised two 24h races on rfactor. I don't see a reason why it shouldn't work witch GPL
To make it more fun, we could use a rolling start
Races will feature a rolling start.
Once everybody is on the grid and green lights have been shown, drivers will start a formation lap at low speed. Do not overtake, keep a good margin with other drivers.
After the last turn, cars will keep rolling at reduced speed in the starting grid formation.
When the leading car will be in sight of the start/finish line, an admin will give the real start of the race by typing "GREEN FLAG" in the chat.
Thats from HSO rules
