Hello tukai , congratulations on your new car and welcome to the forum ......
I see ol @
dnieves addressed your question.
I reckon the maker of these cars figured that the owners would be good looking and have above average intelligence (because they made this choice of this car to buy) so they could estimate the miles to empty from looking at the fuel gauge ......
I remember back-in-the-day I had an old VW bug that would let you know that you were getting low on fuel when the engine stopped running ...... until you reached down and flipped the lever to open up the reserve tank.
Now, we have "miles to empty" indicators; lights that come on; gongs that go off ........ for those drivers that are so distracted and/or impaired that they don't notice the fuel gauge ......
