1st, reach 6th gear, then follow the road... I did 1:19,75 in 5 minutes.
No real interest, except maybe for live race, with a car different than Indy.
Mno, you made a bad track. :?
Design : 1 : no scenery, always banked corners, ...)
Fun : 2, just because I like 6th gear, but this one has too much of it
Competition : 1 : no interest, everyone will have the same time and I wouldn't like to race 10 times on it to earn a few 0.05 seconds...
