i raced the silverstone gp and i liked it. what i didnt like: that i have to wait a Long time befor the race start.
and you can do nothing as wait.
if you could reserve a startingplace till 5 min befor the race starts would be solve this problem. if you dont come, your Reservation forfeited.
3 forfeited reservations mean you cant reservate until you had a race.
so i think turn 10 could bring more of endurence hoppers and the People must not waste so much time during they wait.
