So I've done some races with the boxer cup in Montreal, and I've noticed something. If I set a race by time (tried with 50 minutes, which is roughly 29 laps), the AI stops half way through (around lap 14) for fuel and tires. But, if I set the race for 30 laps, they won't stop. Ever. I guess they will stop if I race like 200 laps before they ran out of fuel. Is there a way to enforce the AI to make at least one pit stop, while racing with laps, not time?
