Automobiles have, since their invention, revolutionized transportation, changing forever the way people live, travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today the application of puter technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents.
