Advanced driver assistance systems can support a driver in specific situations, but their names can hide important differences in capability.
What to Consider
Automatic emergency braking, adaptive cruise control, lane warnings and blind-spot systems use different sensors and control strategies. Performance depends on markings, weather, lighting and software.
Practical Perspective
Drivers should learn system limitations and when assistance can disengage. A lane-centering feature is not equivalent to a vehicle that can safely operate without continuous driver supervision.
Expert Perspective
NHTSA emphasizes that currently available driver-assistance technologies do not make today's vehicles fully automated and that drivers remain responsible for operation.
