Same thing here, AI cars not knowing they're about to run out of fuel and just grind to a halt, also a timed race.
Can only comment on the FZR really at this point, as they ran out about 10min ago, the XRRs are all sitting in various gravel traps and the FXRs are leading the way but will eventually run out of fuel
Im betting it wont take much to fix, probably just an oversight, but at least its getting there.
The fuel calculations at the start were interesting to see, nice knowing they dont just stick 100% fuel in and keep on going and instead devise their own strategy of sorts.
Also, a question about the AI while im thinking about it, half the FZR's which ran out of fuel also picked up a puncture the same lap, and its got me wondering whether they pit for damage & tyres, though im guessing they wont revise the strategy based on their findings (ie flat 60% into their intented stints).
