When Ralph Nader’s book Unsafe at Any Speed – The Designed-in Dangers of the American automobile was published in 1965, it challenged the political consensus that the automotive manufacturers – Ford, GM and Chrysler – could be trusted to develop and market ‘safe products’, without any need for federal regulation.
By 1965, the steadily rising toll on American roads had reached 47,084 fatalities / year – which had become the socially accepted price of the freedom to travel and resultant economic prosperity.

When asked, ‘industry experts’ argued that, – these deaths and associated injuries were the unfortunate result of poor highway design, inadequate driver training or lax law enforcement, or reflected the growing popularity of ‘affordable motoring’, – in fact anything that would deflect attention from the ‘inherent safety’ of their products.
So, the suggestion that cars should be designed to be ‘crash resistant’ to protect people, – occupants or pedestrians, – in the event of an accident was quickly dismissed because, – the potential benefits were minimal, – it wasn’t technical feasible and the costs of implementation would be extortionate.
Besides, the industry already knew how to sell cars – and that certainly didn’t involve discussing safety in the showroom. Customers who had been persuaded that the real problem was other people’s poor driving – were simply unwilling to pay for unnecessary ‘safety features’.
According to the industry, ‘Regulation’ was completely unnecessary, – it would limit customer choice, stifle creative innovation and increase costs, without solving the problem. So, they argued that regulation should be limited to the harmonization of the rules in different States, adopting the minimum specification of products already in the market as a new common standard. Even attempts to mandate the technical requirements – such as seat belts or collapsible steering columns – for vehicles owned and operated by Federal Agencies was, apparently, an example of ‘federal overreach’ into the affairs the individual States, threatening the US constitution.
So, drawing on his experience as a lawyer seeking compensation for accident victims, Ralph Nader explained how the industry was using it’s economic and political power to suppress the information that consumers needed to assess the safety of new models, or select a ‘safer car’.
The Chevrolet Corvair introduced in 1960 was an interesting, but particularly controversial case study.
Developed to compete with lighter and cheaper European vehicles, such as the VW Beetle, and expand the market for ‘family cars’ the Corvair had:-
- A unique air cooled, 2.2 Litre, horizontally opposed 6 cylinder engine engine – known as a flat 6 – installed in the rear of the car, with the fuel tank in the front luggage compartment.
- But, with the engine at the rear, the vehicle was ‘tail heavy’ and could develop severe over-steer during cornering, that many driver would be unable to control.
- So, to reduce the risk of over-steer, Chevrolet recommended that the front tyre pressure should be reduced to 15 psi – (compared with a more normal 30 psi at the rear) without explaining the dangers of over-inflating the front tyres to drivers.
- The Corvair had a simple wishbone rear suspension, with a coil spring and damper on each side. So, the camber angle of the rear wheels would change as the load on the suspension varied, but during extreme cornering the outside rear wheel could ‘tuck under’ the body making, making the vehicle unstable.

From Chevy Corvair – The Weird, Quirky, Cheap and Yeah COOL Compact
According Ralph Nader, the 1960 Corvair was inherently unsafe because –
- During normal driving, the Corvair could develop severe over-steer causing the driver to loose control and spin out of control.
- While, the rear suspension geometry could cause the Corvair to spontaneously roll-over during a fast lane change maneuvers or brisk cornering – when the outer rear wheel ‘tucked under the body’ – jacking up the rear of the car.
Within months of the Corvair’s launch specialist companies had developed an after-market kit of parts to improve the Corvair’s handling and reduce the risk of spontaneous roll-over accidents. But it later emerged, a similar modifications proposed by Chevrolet engineers had been rejected by the company as too expensive to fit in production.
So Nader argued, before the vehicle launch Chevrolet –
- Knew about the risks of over-steer, loss of control and spontaneous roll-over.
- Knew how to mitigate or eliminate the risk.
- Made a conscious choice to sell an ‘unsafe product’ to maximise their profits.
- Took no action to warn consumers about the known risk.
But, many of the other design choices made by Chevrolet also increased the risk of death or injury in the event of a crash, for example –
- Seat belts and seat belt anchorages were not provided, or available as optional equipment.
- So, in a crash the unrestrained occupants would strike the the hard surfaces of the vehicle interior, which had protruding knobs and switches that could cause traumatic injuries.
- The steering column – a strait shaft – was connected to the steering box, mounted on the chassis in front the front wheels. So, in minor frontal impacts the column and steering wheel could be driven like a spear into the driver’s chest causing fatal injuries.
- The position of the fuel tank, in the front luggage compartment increased the risk of fuel leaks and fires in frontal impacts
Nader argued that the problems with Corvair were a symptoms of fundamental problem in an unregulated market economy, companies will sacrifice public safety to maximise their profits. But by, controlling consumers’ access to information and buying political influences, Ford, GM and Chrysler had also become unaccountable for that ‘trade-off’.
So, the only just cure would be effective federal regulation of design standards with mandatory product recalls when vehicles were found to be unsafe.
For Corporate America this was an intolerable heresy, attacking very the foundations of their economic and political power. To them it it was obvious that federal regulation and enforcement would ‘destroy jobs’, ‘stifle investment’ and weaken the America’s global power. After all they had created employment for millions of people – and unlike this unpatriotic, socialist upstart, talking about social justice and the right to life – they knew how the create wealth!
However, the book’s publication proved to a pivotal moment in the the history of automotive safety, leading to the introduction of the first Federal Motor Vehicle Standard (FMVS) and a system of mandatory product recalls that has evolved into the TREAD ACT. But perhaps, the most significant changes have been driven by public access to information about the safety of particular models – allowing customers to evaluate product safety when choosing a new car, in turn creating a market demand for safer products.
Recent statistics shows how the significant improvements in vehicle design – to make them ‘crash resistant’ and the the development of new technologies – such as stability control and anti-lock braking – have in fact reduced the fatality rate (deaths / million miles travelled) – but the this has been partially offset by increases in the population and total miles travelled since 1965.

But this raises some important questions –
- Would any of these improvements in safety since 1965, have been achieved without Federal Regulation?
- Does an unregulated free market give companies sufficient financial incentives to invest in public safety?
- What level of safety should we expect from fully autonomous vehicles?
In 2025, under the current US administration, Corporate America is reasserting control of the political and economic agenda, while regulations designed to hold them accountable are being rolled back, in the belief that ‘regulatory freedom’ will ‘Make America Great Again’. So, many of the arguments used in the past to block federal regulation of the automotive industry are now being revived, as we contemplate the application AI and other technologies.
Product Liability Law and Regulation are about striking the right balance between the rights of individuals and their suppliers who provide the the goods and services we rely on, – as consumers or employees and investors. But, in a democracy, who should have the political and economic influence to ‘control the narrative’ and set political priorities?
