The automotive industry has reached a stage categorisation of the degree of the automation has become crucial. According to the levels of automation defined by SAE, the automotive industry is already past the first four and development is now being heavily concentrated on level 5, that is, driving independent of human control. This obviously requires an array of sensors, microcontrollers and visual feedback systems like cameras, LiDAR (Light Detection and Ranging) to be present in the vehicle. With security concerns omnipresent among these devices, they are now ported to the realm of vehicles and must be tackled so that unsafe driving conditions are never experienced. In this paper, Section 3 elaborates upon the technologies that have shaped autonomous cars into the form known today and Section 4 explains the network architecture and network security amongst these cars. Section 5 describes the rippling effect of this evolution in the automotive industry on other supportive industries, Section 6 talks about the challenges posed to the development of AVs and finally, Section 7 discusses the future of autonomous vehicles in India.
