The Isuzu D-Max has a digital display that tells you how many kilometers you can drive with the remaining fuel.
The problem: once you reach the lower fuel levels and the warning lamp comes on, the display swaps “320 km” (or whatever) for a single, useless message: LOW FUEL.
The one moment you actually need to know the range, when you’re calculating whether you can make it to the next gas station, the information disappears.
The car knows the number. It just refuses to show it. Why would anyone design it this way?
Three possible reasons:
1. CYA engineering: Some idiot in legal or compliance decided that showing a range when the fuel is low creates liability.
2. Requirements-driven development: The spec said “show range when fuel level > reserve, show LOW FUEL when fuel level ≤ reserve.” The engineer implemented the spec. QA tested the spec. Nobody asked “is this actually useful?” because nobody was driving the car (or a car in general)
3. A complete disconnect from reality: The person who approved this UI never ran out of fuel at night on a rural road.
They sat in a climate-controlled office, looked at a statechart, and decided this behavior was “correct.” It is correct on paper. It is useless in practice.
The D-Max’s fuel gauge is a perfect exhibit of what I’ll call Engineered into Stupidity, design that follows abstract rules while ignoring the actual human holding the steering wheel.
