Right now gasoline is not "cheap."
US numbers, here. Circa 1995, 87 unleaded held at $0.99 per gallon for as long as gas station operators could hold on because they were deathly afraid of being perceived to cross the $1 mark. That's $1.98/gal in today's money adjusted for inflation. That was cheap. That's actually cheaper in inflation-adjusted terms than it was in your parents' golden years when they claimed everything cost a nickel. Cheaper even than it was in 1964 or even 1955.
