This chapter analyses the market regulations applicable to vehicles and the car industry. It discusses how regulation and market forces interact and how regulations are often a result of market pressures. One particular dynamic of the car industry is key to European regulations. The car industry, at least in the European Union, including the United Kingdom, is dependent on complex supply chains, and the industry is in many ways a ballet of logistics and supplier interactions. The chapter describes a continuing member through the European Economic Area agreement or some tailored equivalent, or through the current Government’s withdrawal agreement provisions which will seek to maintain these regulations. It shows that innovation is not limited to the auto manufacturers, and they ultimately need to be prodded through regulation into adopting technology that has demonstrated the ability to save lives. Technical regulations, largely relating to safety, underpin one set of vehicle production and manufacture regulations.
