This chapter explores the development of self-driving cars and the implications this technology has for the future. It examines the approaches taken by leading companies such as Waymo, Cruise, and Tesla as well as the levels of autonomous driving. It discusses the ecological benefits of self-driving cars, emphasising how well-coordinated robot taxis could reduce CO2 emissions. This chapter also addresses the potential societal impacts, including changes in car ownership and the integration of self-driving cars into urban and rural environments. This chapter analyses safety concerns and driving capabilities, noting the cautious driving style of autonomous vehicles and the challenges they face in complex traffic situations. This chapter discusses smart cities and intelligent infrastructure, emphasising the role of the Internet of Things (IoT) in enhancing the functionality of self-driving cars. Finally, this chapter presents both utopian and dystopian scenarios for the future of self-driving car services. It calls for collaboration between technology companies and municipalities to ensure a positive transition towards optimised, coordinated robotic taxi services.
