In this article, I review the legal and regulatory obstacles to the introduction of autonomous vehicles. I provide an overview of the key legislation which is relevant to the introduction of autonomous vehicles in England and Wales. I discuss the motor liability and insurance implications of the introduction of autonomous cars and the legal framework for the testing of autonomous vehicles on public roads. I conclude that there is likely to be significant volume of emerging legislation that car manufacturers and suppliers will be required to navigate as they launch increasingly autonomous driving systems. It is also likely that we will see an increase in the volume and complexity of litigation involving parties such as vehicle manufacturers, software companies, suppliers and mapping agencies.
