Off topic but this is a real gripe of mine - analogue speedos that go all the way up to 240 kmph (~150 mph). I am only ever going to do half that speed, so why not just make the dial go to only 120/(80) and give the needle (and me!) twice as much precision!

You probably would better like a digital display that shows a number instead of a needle

Some cars also use unevenly spaced tick marks on an analog dial. Nice in that it gives you the sweep needle and range of scale without overly compressing the range of most interest.

Analog tachometers for race cars do/did the the same thing:

Many gauges are typically designed to work best in the center 50% of their range.

Maybe limit the dial at 100mph?. Doing 80 on the Interstate near me will get you passed by the impatient. But the real question is why do you need that much precision?
