Whether or not that is true, I suspect it is, the best way to avoid fines for breaking traffic regulations is to not break traffic regulations. They can't make anything from you that way if you do.

Until they start changing speed limits, adjusting the timing on yellow lights, or just saying you ran a stop sign when you didn't and - oops! - they happened to have their dashcam off or their car angled so the actual intersection was just out of view.
