Obviously, I took the picture above while I was going almost 80 KPH on the road. Kids, don’t try this at home! (Or rather on the road, for that matter.) I took it because it shows all three dials pointing in roughly the same direction. I learned way before that in fourth gear, the speedometer and the tachometer move almost in synch. So it’s just a matter of having the gasoline tank full and driving at 80 to get this coincidence.

The dashboard display is from our ’06 Honda City, and I was driving along South Luzon Expressway going home when I took that picture. Actually, I took several pictures and the one shown above was the clearest. My camera’s Image Stabilizer can’t compensate for the vibration.

Well, what I really wanted is to take a picture of our Tamaraw FX’s display. It has four dials: a speedometer, a tachometer, a fuel gauge, and an engine thermometer. Making those four dials point in the same direction is much harder than with the City. But it doesn’t involve an overheating engine to make the thermometer point in the right direction, thank God. The coincidence there can be done by having the engine at normal temperature, the gasoline tank 3/8 full and the speedometer going at 80 KPH with the odometer at almost 3000 RPM in fourth gear.

Finally, there is no such word as “isoangular.” I just made it up because it sounds more scientific than “equiangular,” which is the correct term.
