UnverifiedTesla FSD still belongs to the SAE L2 level of driving assistance systems, requiring the driver to continuously monitor road conditions and be ready to take over at any time.71% similarUnverifiedL2 assisted driving relies on the driver taking over at any time, so the driver monitoring system (DMS) becomes a key part of the safety design.69% similarUnverifiedThere is an essential difference between advanced driver assistance systems (ADAS) and fully autonomous driving: ADAS requires the driver to monitor at all times and take over at any moment, while fully autonomous driving (L4/L5) requires no human intervention but is currently tested only in limited areas and conditions.63% similarUnverifiedL4 autonomous driving means that within a specific operational domain, the vehicle can fully autonomously complete driving tasks and monitor the environment without human takeover, but is limited to specific geofences or weather conditions.62% similar
