Eventually I'd like to see all of these, but realise it will take a while before that happens. I can dream though
-Willow Springs or Buttonwillow (either would be great due to the numerous configurations)
-Brands Hatch
-Donnington Park
-Jerez
-A1 Ring (redbull)
-Mosport
-Vancouver and/or Toronto's old Indy street circuits (O Canada!)
-I think the old Isle of Man motorcycle street track would be unreal!
-Fuji
-Pike's Peak hillclimb
-I know it would never happen, but the Knox Mountain hillclimb from my hometown of Kelowna BC lol
-Daytona (both oval and road, obviously)
-The Bugatti course at Le Mans
-Autodromo Enzo e Dino Ferrari (Imola)
I'd also love to see all of the F1 GP tracks. Again, a tall order, I guess I'll put them in some sort of order of personal desire.
-Spa*
-Monaco*
-Yas Marina
-Valencia
-Malaysia
-Singapore
-Brazil
-China
-Turkey
-then all the rest in no particular order
* I would love love love to see both of these tracks, but am a little worried they would be hit pretty hard by the T10 'widening and straightening' nurf bat.
I will definitely second the idea of a Wangan/Tokyo inspired highway track. As stated before, doesn't necessarily have to be at night (dawn works quite well). But ya, something 3 or 4 lanes wide, looooong, and multi-directional. Let us 'cruise' at 200mph +!!!
And if this is a 'wish list', I would actually totally wish for all the major/'famous' sections of Tokyo's highway system (basically the map from TXR3), but due to it's enormity, would totally settle for both directions of the C1 (of course, along with a 'Wangan' section on a separate track if joining the two together is too large)
...I know, I'm pretty easy to please
