NOVA investigates the innovations of scientists and engineers as
they work to design safer cars.
The program:
-
relates the invention of shatterproof and safety glass.
-
outlines "crash science," which involves understanding the
forces that injure the body—in every accident two
collisions occur: when the car collides with an object and when
the passenger collides with the interior of the car.
-
notes the development of the single most effective safety device
in any vehicle—the three-point seat belt.
-
follows the introduction of crumple zones and a very rigid
passenger cell to reduce injuries.
-
follows the development of the air bag, invented in 1952 and now
being redesigned to address deployment challenges.
-
reviews new technologies under development, such as smart cars
and automated highways.
