NHTSA has long praised automatic braking systems as a safety win,
but the technology has only recently started rolling out on a wide
scale. Using forward-looking sensors, automatic braking can slow or stop
a vehicle that senses it's at risk of colliding with a car, pedestrian,
or other object ahead of it, even when the driver takes no action. Like
many high-tech systems, automatic braking first started showing up on
luxury vehicles over a decade ago before trickling down to the
mainstream; nowadays, it isn't difficult to find a sub-$40,000 car that
has it, but the agreement is intended to ensure that automakers stay on
the path.
Automatic braking, like lane keeping and dynamic cruise control, is
considered a precursor to fully autonomous vehicles. And actually, you
can go back even further than these high-tech features: technologies
that we take for granted these days — like stability control and
anti-lock brakes — paved the way for computer-controlled cars, and some
of these long-established safety technologies are already mandated by
NHTSA.
