Elon Musk: The travel cost of Tesla Robotaxi will be similar to that of buses. In response to the post, Musk said that the battery pack is too small for buses, and Tesla can even operate well in areas near the Arctic Circle. When Tesla releases an unsupervised fully autonomous vehicle, buses will no longer be needed by people. Because Tesla can transport people from the starting point to the destination at a cost similar to that of a bus.
