You can't fly off the track in Forza.
True - you cannot fly off the track in Forza for two reasons;
- There isn't anything outside the track to fly into.
- Your car would be reset before you could reach it.
QUOTE
the car is reset to the track almost immediate when all four wheels leave the track
True expect from fall through the ground glitch. However the question was to fly of the track, not go through it in an endless falling.
Your statement
QUOTE
its when your car tilts too far that it gets reset
is incorrect.
The car will be reset when two wheels are of the ground for more than a few seconds. - Try grinding on a curve on The Ring.
I don't know what you define as a jump, but if you actually get some speed up and hit a jump the car will quickly be reset when all four wheels leave the track, tilted or not. - Try the jump on Alpine Ring in example.
