You must have noticed the inaccurate behavior of your gas gauge, i.e. it’s full and empty for long stretches of time.
The psychology behind why is interesting.
The imprecise nature of the gas gauge is something that has always struck me as odd.
Different auto makers create different tolerances for their gauges, e.g. an old Honda we had stayed on F forever, indicating how frugal it was, my current Jeep starts warning about low fuel with what looks like a quarter tank remaining.
This creates a problem with an unfamiliar gauge, especially when the tank seems to be getting low.
It does seem to be nigh impossible to drive a car completely out of gas, which seems to be a good thing, until you realize that people account for their experiences with the gauges when driving on E, stretching them to the dry point.
I suppose I’d prefer a percent remaining indicator, but that might lead me to madness, e.g. one of my cars has a range calculation for the tank, but its up/down fluctuations make me drive erratically.
Anyway, the gas gauge presents an interesting design challenge. Thoughts?
