From what I understand, they test every car they build on this track. So expect your brand new Ferrari to have a few miles.
I
included an overlay based on a brand new SVG and polygons for two
possilbe routes around track. Note: others were possible, but because
drivers might choose their route while out on the track, I left it at
that.
I also noted a few other details. However, while the factory is right there, I didn't have a map of it. So I left that out.
