True, but how many of use ever had time to learn that? This is the kind of game details that will help if it is revealed before anything gets started. Real track officials would have made the weather or track issues clear before hand at a drivers meeting. If you can do you best to test the conditions on your own it will really help. If not, then join as early as possible and please ask "what if". I knew what to expect, but I had to learn the hard way about the pit exit line, and where the game draws the limit. I had to suffer a DT, but now I learned.
After seeing many of the replay videos we have, it is clear to me that drives are not careful about staying INSIDE the white lines, all the time. Karma will always level the field, IMO.
On the subject of FOV. It will make you a better driver if you understand how to set the screen FOV with your seating distance from the monitor/TV. It doesn't have to be exact, but will really help to find your way around a corner faster. Some of the video replays show such a wide view that its now wonder their not the lead car. Project Car 2 has more info on this subject. Or, 'oogle it!
