034 Car Interface

Recently I read about Tokyo Olympics 2020 and the plan to have self-driving cars as taxis, which seems interesting, and this made me think about all the Internet-of-Things and how things are connected; how different devices communicate - who or what controls and manages settings? Is there a main control person? Etc. If there is a chance to choose between manual mode (driving yourself), or autopilot (computer driving), could it pick up these hotspots (cell towers, or from wherever the information is coming, or to where the car connects to). Could the car and the areas interact and communicate, or negotiate an ideal speed? Adhering to regulations? Help guide and recommend ideal routes? Is it interfering too much? Too prone to hacking? Regardless, this was one point of view that came to mind when creating this prompt. The interface alerts the driver when driving too fast and reduces the speed to road regulations and conditions.
