Toyota's e-Palette is back in service. As Roadshow reports, the automaker has resumed use of its self-driving shuttle at the Paralympic Games in Tokyo following a collision with a visually impaired athlete. Not surprisingly, both Toyota and the games' Organizing Committee have made changes in light of the crash -- they've determined that both the autonomous vehicle and the circumstances around it were to blame. The company noted there were only two guide people at the intersection where the collision occurred, making it difficult for them to watch all vehicles and pedestrians at the same time. It simply wasn't possible to ensure safety at this signal-free intersection without everyone working together, Toyota said.
