You don't need to read them, look at their relative positions on their dial and have an idea. This is how they work.

When I look at them, I have an idea of my speed within +/- 3KM/h and rev. within +/- 200 RPM. No read, just glance. I let my brain process.

I don't read my car's dials either. Temperature gauge even has no numbers, but three sections: Too cold, normal, too hot. The same dial even has some large, smart hysteresis programmed into it. If the engine doesn't move out of its tolerance, it always shows the middle, meaning "it's alright".

Same for speed, rev and fuel. I just look at the needle's position. Fuel is also esp. problematic because the best you can get is a guess. Unless you "guess and dampen", it'll just move/change all the time.
