To start, I know that cars can go faster than typical speed limits because if you went on a freeway at 100km/h with a car that had the same top speed, you would essentially be pushing it to the limit constantly, which is not really good for the car.
My question is why do cars have their speedometers marked way higher than they can actually go? For example, my dad’s 2017 Toyota Yaris marks up to 220km/h but it could probably go no more than 150km/h tops, so could they not just mark the speedometer up to 150km/h because it’s not really going to go above that?
EDIT: FYI I live in Australia

The other people suggesting the positioning of an analogue needle being easier to read under certain conditions certainly is interesting, never heard of considered that before
But a more mundane answer is car manufacturers not only share parts between different models within a class, but also between classes and also between brands.
So often the poverty spec 1.2 Speedo will be on the higher end 2.0 model too… And even more so, the crappy little 1.2 hatchback might also share a Speedo with the 3.0 sedan… You sometimes even see switch great from a ford in an Aston Martin, as they are owned by the same parent company
