A Silicon Valley startup founded by former Google employees is looking to radically change long-haul trucking. Otto is developing a self-driving truck upgrade kit for commercial rigs. As with the race to develop self-driving cars, Otto is not alone in these ambitions, but self-driving trucks could lead to unintended consequences for local economies, particularly in small towns that rely on the trucking industry. Otto debuted with its plan in a Medium post published Tuesday. The startup highlights the need for self-driving trucks by citing the deteriorating quality of life for drivers, road congestion, pollution and safety.
