17 Pit stops in a race

Hi all,
I noticed during the last race that a driver kept running out of fuel and pitting. When I checked the results at the end, driver had pitted 17 times which I thought bizarre as you can only set up 5 maximum and would of thought that CPU would step in and just put on mediums with certain amount of fuel.
Has anyone else experienced this?

Hi J

If you set the maximum of 5 stints (4 stops) then the AI will simply repeat the last stint over and over. If you only set 4 stints (3 stops) then it will default to medium tyres and highish fuel load.

So if Stint 5 is 3L of fuel and SS that will then repeat till the end of the race.

He can also manually call to pit with a low fuel weight. 

Thanks guys.
He regularly logs in and is at level 18 so it's not that he doesn't know what he is doing.
I'll message him and see what response I get
