Concerns have arisen over China's electric buses, which are currently in use across Australia and Europe. These buses have been found to have vulnerabilities that could be exploited by cybercriminals. Additionally, there is a worrying feature described as a virtual kill switch, which could potentially be activated by the Chinese government. This has prompted the Australian government to review the security implications of these vehicles. The situation raises significant questions about the safety of critical infrastructure and the potential risks posed by foreign technology in public transport systems.
