Self-driving cars set for future highways

It's been more than half a century since some of the first concept cars boasting self-driving features were presented to the world and they're still not on the roads. But many auto executives say the industry is on the cusp of welcoming vehicles that make the idea of keeping both hands on the wheel an anachronism.

General Motors showed off "dream cars" in the late 1950s like the Firebird II and Cadillac Cyclone with features automakers are now starting to roll out in new models as the technology, based on sensors, lasers, radar systems, GPS, cameras and microchips - improves and becomes less costly.

While most industry officials don't envision a fully self-driving, or autonomous, vehicle before 2025, features such as adaptive cruise control or traffic jam assist that automatically slow or apply the brakes for a car in certain situations are already being introduced. And much like anti-lock brakes became the norm after initial resistance, these new technologies will prepare drivers for a future where they are needed less.
