American consumers have benefited from relatively low gasoline prices for extended periods over the past decade. Those periods of cheap gas had a hidden cost that was not always visible: they deferred the adoption of electric vehicles, reduced investment in charging infrastructure, encouraged automakers to focus on gas-powered trucks and SUVs, and reinforced an oil dependence that has now been exposed by the Iran conflict. Rising US interest in electric vehicles at $3.90 per gallon is revealing that hidden cost in the most personal and direct way possible.
The exposure has come through Iran’s closure of the Strait of Hormuz following US and Israeli military operations. That waterway carries roughly one-fifth of global oil supply, and its disruption has elevated crude prices and pushed American retail fuel costs to their highest level in nearly three years. The financial impact — felt directly at every fill-up — is the bill for years of deferred investment in alternative transportation that cheap gas made seem less urgent.
CarEdge’s Justin Fischer documented the consumer behavioral response: a 20 percent EV search increase beginning within 48 hours of the conflict’s start. Edmunds’ Jessica Caldwell explained the psychological mechanism — gasoline pricing’s direct, repeated, and personal financial impact makes the hidden cost of oil dependence suddenly and viscerally visible. The deferral that cheap gas enabled is ending, at least temporarily, at $3.90 per gallon.
The used EV market at sub-$25,000 prices provides the most accessible response to the now-visible cost. Pre-owned Teslas, Chevy Equinox EVs, and Nissan Leafs represent the vehicles that would have been more widely adopted if cheap gas had not deferred the EV transition. Their current availability at accessible prices is itself partly a consequence of the EV investment that occurred during periods of higher gas prices and stronger policy support.
The broader lesson may be that cheap gas was never really cheap — it was cheap in the moment but expensive in its systemic consequences, reducing the urgency of transitioning away from oil dependence and leaving the country more vulnerable to exactly the kind of supply disruption the Iran conflict represents. At $3.90 per gallon, the true cost of cheap gas is being revealed, and US interest in electric vehicles is responding accordingly.
