I have recently been interested in automotive articles such as the next generation vehicles which are electric cars and hydrogen fueled car. I also have focused on self-driving cars. I came across an online article the other day that there still have been some accidents on self-driving cars all over the world so far. Now that you mentioned it, in Japan, it's still fresh in my memory that there was an accident contact between the self-driving bus called "e-Palette" and a blind athlete at the Tokyo Olympic Village in 2021. In the U.S, there was an incident in 2023 that a woman got hit by an another car and got run over by a cab in a row. The cab belongs to the company called "Cruise" which runs self-driving taxies. Unfortunately, it couldn't avoid the woman because she showed up in front of the car suddenly. I leaned that the self-driving system has six levels defined by "Society of Automotive Engineers[SAE]. Level-0 is "No automation", 1 is "Driver Assistance", 2 is "Partial Automation", 3 is "Conditional Automation", 4 is "High Automation" and 5 is "Full Automation". The driving system with over Level-2 can run a car with hands-off which doesn't need to operate the wheel by human's hands. The system with over Level-4 can run a car without a human and the status is called "brain-off" because a car can run on its own even if the driver doesn't need to think anything. However, there was an accident contact between a bicycle not ridden by a human and the electric cart in 2023 in Japan. The cart had level-4 driving system for the first time in Japan back then and the news made waves across the country. I think a self-driving system is still a work in progress. If the system becomes perfect and the world with no accident comes true in the future, I'm pretty sure that we all can enjoy road trip on our own.
