The mentally intricate and stresstospheric process of estimating how much gas there is still in the
tank when there is no way to tell for certain because:
A. the fuel gauge does not
workB. it’
s reached the point where the
tank is so empty, it is pointless to look at the needle for any real information
C. Gastimating
may also be resorted to when the gauge does
work but there are no more funds for refilling the vehicle, thus the import of the Gastimate hinges in figuring out as closely as possible how far it
may go / how long you
may remain in a motor-engine transportable condition with the amount of fuel available. After said combustible liquid is used up, the prior means of transportation magically transforms into a simple sheltering mechanism, protecting against the elements but useless in other ways until gastoration occurs.
Gastimating properly is an essential survival
talent or technique, particularly when driving at night through cities that do sleep and long stretches of empty roads.
