Try the track-condition tag in the track.
track-condition "0.80"
This is an example with the condition set to 80% (asset has build 2.9):
track-condition "1.0" will mean track is 100% perfect.
For the cab view, disable cab motion, or whatever it's called in the 3-bar menu when in Driver or Surveyor. I can't remember which menu specifically, interface settings, maybe, because I'm not at my desktop computer.
