A trapezoid would make the math easy, but you also have to make sure to squish the lines closer together the farther they are from the players view.  The farther points are from the player, the more they are 'squished' in the Y direction.  I'll see if I can draw up the correct math, I think it might be relatively simple

That's what my ENTIRE last post was about. I guess I am bad at explaining things.... Points closer to the wide end of the trapezoid get squished in. That is why it is a trapezoid. The trapezoid is transformed into the rectangle view. Like, if you cut out the part with the trapezoid, and then squished the ends so it was a rectangle, it would look like a rudimentary mode seven.

basically you're wanting to draw a wireframe of the track in 3D instead of the rotating+scaling ala 'mode7' like in fzero? This idea has been mentioned before yet hasnt been overly explored.

Yeah I think he wants to do something like GlassCars, but instead of having slopes, he wants to make everything flat. Basically zDoom/Doom 83 engine with lines at the bottom of the screen instead of full walls.

With appropriately designed tracks the calculational demand per frame might not be too intensive. Of course you wont get as much detail but you would still have a nice track to follow.

Yeah true. If his tracks are very huge and complex, though, he might have to find a way to not have to display everything that is far ahead, like in old Nintendo 64 games when far away terrain did not appear completely.

^^^^ (last four posts?)
My thoughts exactly.
My rotation is not working STILL though, rotating the wrong number of degrees. I think I am close to a solution though, so I will keep yinz posted. Once that is done, all is left is porting to AXE (from basic) and optimization.

Do you have the math locked down or is it the translation to code at this point?

(just wondering how you are calculating your rotations?)

Lod system, level of detail, which decreases when the distance increases
