SAE levels of driving automation

SAE levels of driving automation categorize how much a vehicle can handle driving tasks. Level 0 means no automation; the driver controls everything. Level 1 offers some assistance, like cruise control. Level 2 can control steering and acceleration but requires the driver to monitor. Level 3 allows the car to manage driving in certain conditions, with the driver ready to intervene. Level 4 can operate independently in specific areas or conditions without driver intervention. Level 5 is full automation, where the vehicle can drive anywhere under any conditions without a human driver. These levels help define the progression toward fully autonomous vehicles.
