They've been slowly replacing the flip-disc displays on the buses where I live with LEDs and LCD panels which has been such a shame. There is a beautiful mechanical satisfaction to a panel of flip-discs inverting and I genuinely find them easier to read.
The LED / LCD displays are probably lighter (less heavy), and someone figured they can save 0.001 gallons of diesel a year fleet wide if they replace displays. Net Zero Fatigue is real.
You’re not doing your cause any favors by projecting everything on an ill-fitting frame.
