Here is the F1 track for the USA from Austin, Texas. Circuit of the Americas!
It’s a little long at 5.536km vs actual 5.515km Slope data for most of these tracks is not super reliable, but it is close. At 5.5km I finished it in 2:41.57, which is quite a bit off the pace of the record 1:39.347. This is probably due to the extremely tight curves at each corner and some tricky long esses on both sides which don’t bode well for an American street car, which is what I use. I’m sure many of you will do much better with it than I did. 
[size=50]I keep hoping the devs can make track start directions selectable. 0 for horizontal and 1 for vertical start points perhaps? [/size]
Enough babble, on to the track!
