Speedo Musings: 2

The more I think about using the GPS as a speedo, the better it sounds.

So I mocked-up how I think it should look, based on the TomTom Via 130 I am using.

You could keep the bottom band displaying next navigation action & distance.
But replace the map, most of the time, by a large display of the current speed limit, looking like a speed limit sign, of course.
Then, nearer the driver, an even larger display of the current speed.
This display should change format immediately above the speed limit & again significantly above the limit.

I would suggest white on green up to the limit.

Grey on yellow just above the limit.

Black on bright red (maybe pulsing?) above, say the speed-fine border (+5km/h or +5% above 100km/h?).

Maybe yellow on violet if the GPS doesn't know the limit??
Daltonians should be able to choose their own effects.

Other options could define when the speeds were & were not displayed.
I would suggest they should be shown except in the short zone (150-300 meters) before a navigation action, when spoken instructions are usually given.
With vocal commands, you could call up "Map" or "Speedo" as required too.

All that should be do-able for nothing with current GPS's - just the cost of a few lines of program...
