At the time of the report, there were 10.5 million vehicles registered in Britain, but, at predicted growth rates, this number was expected to become 18 million by 1970, 27 million by 1980 and about 40 million vehicles in 2010, or 540 vehicles for every 1,000 population, equivalent to 1.3 cars per household.
They expected growth in traffic to be uneven, with more congestion in South East England, and to incorporate a population that would reach 74 million.
Buchanan declared:
It is impossible to spend any time on the study of the future of traffic in towns without at once being appalled by the magnitude of the emergency that is coming upon us.
We are nourishing at immense cost a monster of great potential destructiveness, and yet we love him dearly.
To refuse to accept the challenge it presents would be an act of defeatism.

The impact of the motor car was compared with that of a heavy goods vehicle which; 
given its head, would wreck our towns within a decade... The problems of traffic are crowding in upon us with desperate urgency.
Unless steps are taken, the motor vehicle will defeat its own utility and bring about a disastrous degradation of the surroundings for living... Either the utility of vehicles in town will decline rapidly, or the pleasantness and safety of surroundings will deteriorate catastrophically – in all probability both will happen.

Indeed it can be said in advance that the measures required to deal with the full potential amount of motor traffic in big cities are so formidable that society will have to ask itself seriously how far it is prepared to go with the motor vehicle.

There was a need to limit vehicle access to some urban areas:
Distasteful though we find the whole idea, we think that some deliberate limitation of the volume of motor traffic is quite unavoidable.
The need for it just can't be escaped.
Even when everything that it is possibly to do by way of building new roads and expanding public transport has been done, there would still be, in the absence of deliberate limitation, more cars trying to move into, or within our cities than could possibly be accommodated.

Already the growth of vehicle ownership in America had not been held back by congestion in urban areas; they observed that congestion in Britain's smaller land mass might limit the use of cars but probably not affect people's desire for ownership as they became more affluent and hoped to try to use their cars.
They saw the day coming when most adults would take the car "as much for granted as an overcoat", and value it as an "asset of the first order".

There would also be pressure to house a growing population and disperse more population away from overcrowded cities.
However, dispersing the population around the countryside would be synonymous with urban sprawl, and would defeat one of the reasons for car ownership, to get out into the countryside.
Having examined the road network in Los Angeles and Fort Worth, Buchanan wished to avoid their dehumanising effects and their creation of pedestrian "no-go" areas.
He also wished to ensure that the heritage within British towns was respected:
The American policy of providing motorways for commuters can succeed, even in American conditions, only if there is a disregard for all considerations other than the free flow of traffic which seems sometimes to be almost ruthless.
Our British cities are not only packed with buildings, they are also packed with history and to drive motorways through them on the American scale would inevitably destroy much that ought to be preserved.

The rise of traffic congestion would waste people's time, who would soon have to spend time sitting in traffic, in addition to their time spent in sleep, work, and leisure.
Already, the average speed in many cities had fallen to 11 miles per hour (18 km/h), and congestion was costing the British economy £250 million in wasted man hours.

Yet the motor car was also inextricably linked to the economy, with 2,305,000 people working in the motor trade, or 10 percent of the labour force.
It had already eclipsed the railway
