Sorry but have to say something about that you said.
Wangan can seem to be just press Forward and thats all, but if you now about race and so you can see it has also challenge even with ghost:
-With Ghost: you need to take the few corners perfecto to mantain the speed because in the first corner 80% of the people tend to crash and lose speed and because that the race (including me sometimes xD)
-Without Ghost: Its a race of Strategy, you need no only take the corners good but now how and when to Draft, drafting at the perfect moment can give you the win even againts cars better than yours, in this track the draft its the key.
So man if you say "Wangan requires 0 effort" to race, you are really wrong and need to learn more about cars and races :3
if theres something im wrong and the more experienced than me saw them please tell me, i want to learn more
