The autonomous vehicle technology has developed rapidly in recent years. Many developed countries have revised the related laws and regulations in the industry in order to support enterprises to conduct research and development and test of autonomous cars. In general, western countries have gradually recognized the legal status of autonomous vehicles in legal principles. In addition, Chinese government also decides to put forward policies to support autonomous vehicle technology. Chow (2018) points out that Chinese government regulates that by 2020 half of new cars sold must have full or partial autonomous functions. In 2017, Beijing government promotes policies to allow autonomous vehicles to be driven on the city’s road after they pass the test in a closed zone. Influenced by Beijing government, an increasing of local government will release policies about autonomous vehicles policies, which may be beneficial for the development of autonomous vehicles. 3. Assessment of Risk unmanned driving technology is still in development, the key technical difficulties and bottlenecks have not been completely solved, and technical safety is still a huge problem. One of them is the system failure caused by temporary network interruption, which leads to the risk of traffic accidents. For these technological risks, the most important thing for enterprises is to strengthen technological research and development, and strive to break through the bottleneck of technology. (责任编辑:周海霞) |
