The Car Was Built for a World of Cheap Oil

There’s a reason the car didn’t just succeed. It took over.

It offered something no transport system before it could. Personal freedom at scale. Not just movement, but autonomy. You could go where you wanted, when you wanted, without asking permission, without waiting, without sharing.

And crucially, it was affordable enough to become normal.

That combination changed everything. Cities reshaped. Economies reorganised. Entire ways of life formed around the assumption that individual mobility was both possible and permanent.

But that success story rests on something we rarely talk about.

The car belongs to a world of abundant oil.

Not just for fuel, although that is the most obvious part. Oil runs through almost every part of the system.

The plastics in dashboards and bumpers

The synthetic rubber in tyres

The lubricants that keep engines running

The coatings, sealants and wiring insulation

The global supply chains that move parts across continents

The modern car is not just powered by oil. It is made from it, assembled through it and delivered by it.

This is what the diagram shows. Oil is not one component. It is the system behind the system.

The Turning Point

We are now in a period of transition.

Stories about Western carmakers hesitating on electric vehicles miss something important. This is not about whether electrification will happen. It already is.

More than 10 million electric cars were sold globally in 2022 and the numbers continue to rise. Electric vehicles could displace around 5 million barrels of oil per day by 2030. A typical petrol car uses roughly 11 barrels of oil every year just to run.

That last point matters.

Electrification does not just reduce emissions. It removes the ongoing oil demand from every vehicle across its lifetime.

That is why, in the medium term, electrification is unavoidable. Not because it is perfect, but because it directly reduces the largest source of dependency.

What Electrification Cannot Fix

There is a harder truth underneath this transition.

Even if every car becomes electric, the system itself does not fundamentally change.

Cars still require oil based materials such as plastics, composites and synthetic rubber. Manufacturing remains energy intensive. Supply chains still depend on global shipping networks. Large volumes of raw materials are still required.

Electrification reduces oil use when a car is driven. It does not remove oil from the system.

It also does not address scale.

There are around 1.4 billion vehicles on the road globally and that number is still growing. Even as electric vehicles increase, overall demand for resources remains high because total vehicle numbers continue to rise.

We are making cleaner cars. We are also making more of them.

Each one still carries a significant material and energy cost.

A Different Kind of Change

The real shift ahead is not only technological. It is behavioural.

The car succeeded because oil made it easy. Cheap energy made individual mobility widely accessible. That condition is changing.

If resources become more constrained, the model that depends on everyone owning and using a car all the time becomes harder to sustain.

This points to a different kind of future.

Travelling less where possible

Travelling together more often

Designing places so that daily life requires less movement

This is not about removing freedom. It is about changing what freedom means.

Freedom does not have to mean constant movement. It can also mean living well without needing to travel so much in the first place.

Where This Leaves the Car

The car will remain part of society, but its role is shifting.

It will become more intentional. It will sit alongside shared and public options. Growth in the number of vehicles cannot continue indefinitely.

Electrification will help reduce pollution and cut the ongoing use of oil. It is an important step and a necessary one.

But it does not solve the deeper issue.

We built a system on the assumption that resources would always be abundant. That assumption no longer holds.

The question now is not just how we power cars.

It is how much we rely on them at all.
