A few made up courses, a couple of adaptations of real Swedish race tracks and a pair of circuits created by RedGlovesRule99 from
this thread at Jalopnik.
Carrera del Diablo and Mountain Crest Raceway are my own creations, while Gotland Frankenring is based on Gotland Ring in Sweden. Same goes for Grand Gelleråsen, which is based on Swedish track Gelleråsen (aka Karlskoga Motorstadion), although this one is longer due to not being able to get the scale correct (and I'm not sure the track editor would have allowed the corners if smaller). The last two; Seattle Motorsports Park and Red Gloves Raceway (the latter named by me) are creations of RedGlovesRule99 (see above).
More to come as and when I get the time to fiddle around.
As for the track editor, I would've wanted the ability to create sharper corners, and it would've been nice if you could alter track width after starting editing. Or why not just draw the track, and specify length and track width afterwards? Ah well
