This is what I thought Eric was planning on doing with Kyoto... or doing right now I presume. I am not sure though, maybe it would go straight there instead of being a kink like that. Either way, I REALLY want this long version!!
i like the psuedo-daytona 24 hours configureation you can see in you pic..
most of the oval with the infield loop with 2 hairpins thrown in- that would be a fun high speed layout..
I have said this before but that config would suck because the tight hairpin which would be unreal because you would be doing 320km/h in to it, an there would be a concrete wall against you with no run-off area. Hyperactive made a better one I think.
To a point Kyoto isn't used much, but it is mostly because it isn't all that exciting. Are there many places to brake hard and slow down on that track? Not really.
Your small/short config is a good idea and all, but again, think about the lack of slow spots and passing opportunities. That has hardly any, and would be quite boring just driving at the limit no matter what car you use. Because that snakey s-curve area is mostly always flat out and never really much fun after countless laps in a race. I still wouldn't mind seeing SOME kind of short track for Kyoto anyways, it really needs it. This long version would be quite popular I think... especially for endurance races. The only part that I think would need careful planning is where GP meets the Oval and combines with National. That kink people draw out should just be a straightaway so you drive perpendicular to the oval straight.
