The scene is a fast forward movement in a long tunnel.

Shot with a stabilizer, still has some wiggling around.
I want to keep the very far end of the tunel in one place on screen.
Tried tracking the vanishing point, but the focus easily moves away with one of the lights.
There's also a rather constant "triangle" of the road below, obstructed from time to time. Have no idea how to track its top "verticle" then.
Please advice on how to aproach this task?
