The Road to Full Autonomy

L0

What happens: The human driver performs all driving tasks (steering, braking, accelerating) without system intervention.

Example: Classic manual vehicles, basic economy cars without ADAS.

Your Role: Full Control

L1

What happens: The system assists with either steering OR acceleration/braking (not both simultaneously).

Example: Adaptive Cruise Control (Speed) or Lane Keeping Assist (Steering).

Your Role: Monitoring & Hands-on

L2

What happens: The vehicle controls steering AND speed simultaneously under specific conditions.

Example: Tesla Autopilot, GM Super Cruise, Ford BlueCruise.

Your Role: Eyes on Road, Hands ready

L3

What happens: The car drives itself in specific environments. The driver can engage in secondary tasks but must intervene when prompted.

Example: Mercedes-Benz Drive Pilot (select markets/highways).

Your Role: Take-over when requested

L4

What happens: Full autonomous operation within a defined "geofence" or ODD (Operational Design Domain).

Example: Waymo Robotaxis, Cruise (in specific city zones).

Your Role: Passenger (in ODD)

L5

What happens: The system can drive anywhere, anytime, in any weather condition. No human input is required at any point.

Example: Theoretical future concepts; no commercial vehicles currently available.

Your Role: Passenger Only
