Novelist and raconteur Michael Smith explores Britain's modern obsession with cars and driving, as well as seeking to understand the effects it has on our daily lives. Whilst travelling to all corners of the UK, he questions why we love them, what they say about us and whether there is a car out there that even a stubborn non-driver like him could one day fall in love with. Smith gets in the passenger seat with all manner of people who call the road their home, asking how they survive a life of perpetual motion while losing himself in the constant flow and undertow of the road.
