Right, here's another one. Quite a lot going on here.
Four tracks going on here: GP, club, 24hr GT and oval.
GP (21 turns, 5140m, 3.21mi): A mixed track, containing both long, fast straights as well as a tight complex. The entry into 6 and the exit out of 7 is interesting, as it goes underneath the oval course. The key to winning on this track is driving the complex from 8-17 to set yourself up for the 860m straightaway.
Club (6 turns, 2195m, 1.37mi): The short circuit, skipping out turn 5-20 with a wide 168-degree right hander.
24hr GT (24 turns, 6300m, 3.94mi): The circuit used for the prestigious 24hr GT race every year. Instead of taking turn 6, the track ascends onto the oval, round one turn of the superspeedway, and back down onto the main course through two sweepers.
Superspeedway (2 turns, 1600m, 1mi): A mile oval with low banking, the only track variation to go anti-clockwise. The pit lane has an interesting feature: to allow the 24hr course to access the oval, part of the pit lane is temporary, allowing the pit lane to be split into two sections with the track running through the middle. Of course, this is never used when oval races take place.
Roger, your work is normally brilliant, but, I'm not sure about this big round layout thing you've got going.
It works rather well for chaining corners and for more complex corners I start a corner and erase the excess line to adjust the apex and set a new endpoint.
