A recent comment over in the blog got me thinking about the problem that is the track transition, the part when the track changes from downhill drop to the straight away track.
I know we've talked about this part throughout several threads here, but thought a dedicated thread might be a better resource.
The transition is the toughest part of a track to keep consistent and thus fair to all cars. If both lanes (or more) aren't all bending the same way then one lane will probably gain/lose speed. This also means the transition needs a little give as possible so that cars don't lose their energy when they hit that spot. You want the car's energy to transfer into forward motion, not downward motion when it hits a "soft" spot in the track.
Keep the lanes on the level is also a challenge. Keeping the angle of bend is tough but then making sure one track isn't leaning more left/right than the other can be hard too. I guess it's not so bad if all lanes exhibit the same trouble, at least then it's fair.
Anyway, I think it'd be great if you could share your solutions for having a fair transition in your track.
