I did just finish Austrian sprint race in my driver career (100% races and my first season) and of course Verstappen did retire... He has retired 4 or 5 times before that and he is also the only driver that has retired more than one time and this is really frustrating...
And yes this Verstappen DNF problem isn't the only one... AI drivers should make much more mistakes (couple spins i have seen at this point of my driver career) and what i haven't seen yet is AI drivers crashing on each other... I can make crashes against AI anytime but AI driver crashing with other AI driver... NEVER HAPPENS! :/
