As a result of years flying thirsty aircraft back before computers did most of the work, I routinely calculate in my head miles and trips remaining before refueling and compare that with weather forecasts to decide when to stop. However, I am a rare exception among the people I know. Most of them, particularly the women, get gas either at a set point on the gauge or when the low level light comes on. I can see where a car with less than common range and limited refueling options would not be comfortable for a lot of people.
