It is because 80% car owners only drive some maximal 20 kilometers per day, this needs mostly only 2 liters, so 2 dollars a day, 60 dollars a month, for the car owner that’s well about 360 to 400 RMB (1 dollar = 6 RMB), while for those car owner’s family their netto month income is about 8000 RMB average, so that’s some 5% of the income.
