Apparently the ´First 5 not allowed to pit under code 60´ rule applies to the first 5 cars overall. No specific reason is given for this measure but it seems to be done to enhance competition... (did Creventic do a little internship with Nascar perhaps?
).
Also there is a ridiculously complicated procedure for top 5 cars that do pit under code 60 when they threaten to run out of fuel.
Completely in the woods on why Creventic came up with this little bit of ´voodoo´.....
