In the past, the bus only focused on the efficiency of capacity and transportation. The distance between people was close, and uncomfortable. At the same time, problems also emerged: infectious diseases, sexual harassment, barrier-free, etc. . Especially under the COVID-19 , people's lives have been completely changed, begun to fear crowds and contacts, and pay attention to personal space. Therefore, a bus that can solve these problems and combine future trends is designed for 2030, which people can enjoy private space and a safe riding experience.
