Not at this time but maybe in the near future?
The "digital" readout has nothing to do with your speed. It's just a digital "display" as opposed to an analog type "needle". Your tach only shows the engine revolutions, it just gets you TO the speed via your transmission.
By the way most cars have had electronic/digital speedometers/Tachs for years.
The tach is completely separate from your GPS-anything. The tach is controlled by the on board computer which controls ALL your engine and transmission information.
Maybe in the future the feds will "help" us drive better and have the vehicle only go as fast as the speed limit. More then likely it will control the speedometer and not the rpms. And more then likely from sensors in the ground as the satellites can have blind spots in tunnels, large trees, large downtown buildings in cities, etc. Satellites have to have "line of sight".

How might satellite mapping help historians?
Satellite photography, if done relatively close-up, can show discolorations in the ground that are invisible if you are standing there. Those discolorations indicate - often very clearly - the outline of ancient roads and buildings that once were located there. This helps archaeologists to dig and search in the exact right spots.
