Super speedway course /world

In real life motorsports there are big super speedway courses that are extremely fast and flat (aside from the banked corners) and also fairly flat on the infield section.

Got me thinking, something like this on Zwift would be perfect as an always on world for pace partners groups to go on always flat rides which a lot of people like. A super speedway wouldn’t be too hard to build because it’s a limited space.

It would also probably be handy for testing pace dynamics away from races or the wider Watopia world.

This would also be an alternative to velodromes (asked for before) which would be too small for typical numbers of riders in Zwift

Something like this:

But also using the entire outer-oval as well (so multiple different combinations of courses)
