At this point I've raced enough, I haven't seen a safety car so I'm guessing there is none.
Couple quick thoughts. For the most part these are real life situations that were present in the Motorsport Manager game (which I'm guessing most folks were fans of), and even though I love this game, I kind of miss these simple features.
1 - Consistency: I don't know what the algorithm is for consistency but my suggestion would be to make drivers a little more inconsistent. Even a low level driver is incredibly consistent. If you are behind, doing about the same lap times you have no hope of catching them, whereas in real life if they made a few mistakes (locking up the tires, spinning out, etc) you could catch them.
2 - Crashes: Similar to consistency, if your driver is really pushing it at a track like Monaco there is a chance they may crash out all together. This adds a whole new element of the game. "We're behind by 6 seconds, 10 laps to go. Do we even try to catch him and risk wrecking?"
3 - Safety Car: Perhaps the most obvious, but I think the safety car adds so many elements of strategy that it's a real shame it isn't present. A fair number of tracks have a safety car almost every race, which really requires you to take the SC into account when planning your strategy.
Anyway, just food for thought. What does everyone else think?
