I don’t think the cautions should be scheduled. If the race is going well and everyone is bunched up there’s no need for a caution. If there are many spins/wrecks a caution would be useful to clean up the mess and bunch the field up. I don’t see the value in scheduled cautions unless we are limiting the amount of fuel to be used.
The problem I see with this is everyone will want a caution as soon as they spin out. How many wrecks and spins will determine a caution plus the admins would like to race as well.
How about “gentlemens cautions”? Whoever’s leading at the time drops to pit lane speed and we all catch up. That way the admins don’t have to worry about triggering a caution and interrupting their fun.
