Rescaling the speedometer

I remember a time when car speedometers ended at 180 km/h, our P307's speedo goes to 210 km/h. I've only gone to 150 once, when we bought the car, since then I try to keep my speed below 100-110 km/h.

We are looking at getting a new car, and almost all of the models I've looked at go to 230 km/h, even though I searched for "eco" models.

Why do I need a speedo that goes almost twice as fast as I'll ever need to? Except for the Autobahn, most highways in Europe are limited to 120 km/h (140 in Poland and Bulgaria). Why not re-scale it to 0-150 to get better resolution?

Question is: How would I go about doing that? It's not enough to print a new background, I need to reset/recalibrate the step motor (or whatever it is) that controls the position of the speedo indicator needle. How?

Then there is question of how legal the new setup would be...

What matters is where you're going, not how fast.
