The camera usage is amazing. My car shows current speed

It does. We noticed this years ago when there was a large
scale change throughout the state to expand town/city
boundaries and often the garmin device with its advisory voice
was clearly wrong about when the speed limit had changed.

Seems it would take only a small step in software to limit the
speed to what the sign showed.

Well, that would require some sort of vision system. The GPS
devices and smartphone apps don't typically have that capability.
