What has the prisoner's dilemma got to do with road traffic? Could we replace our trains with rollercoasters? Would putting spikes on steering wheels decrease road collisions? These questions (and a bunch of others) will be explored, introducing you to some basic concepts of transport science. A variety of thought experiments will be subjected to the limits of physics, engineering, economics, and psychology. This will show why the transport we already have is in fact an immense success! Transport is a sector that affects the everyday life of most people and needs to be continually funded, reviewed and improved to sustain civilisation. This book will arm you with the tools needed to tear political propaganda to pieces as politicians push for transport solutions based on ideology rather than facts.
