If you have one of these cars, you are going to have to have friends with one to get the most out of it. Keep your eyes open for people mentioning they have one and send them a friend request, mention the F1 in the request. I dont know for sure, but seems a logical explanation, that Ferrari did not want their cars being raced against anything else and made PD implement this. Which is also why there are two to choose from. When looking through lobbies, I can see what people are doing before I enter a lobby, hover the cursor for an extra second and the lobby current status will pop up. In my experience usually if theres an F1 lobby, they will name it accordingly, so if you have one, join that lobby and add them as friends. If they went the work to get one, most likely they will drive it wisely. If you are the only one you know with one, it will seem quite useless, dont be that guy. I dont anything about Arcade or practice, doesnt seem as fun as racing with real people to me...
