People driving in bad weather, at night or on slippery roads will be able to enjoy a greater sense of security, thanks to new cutting-edge technology developed by Japanese automakers.

The carmakers, whose safety technology once focused on minimizing injuries in an accident, are now racing to develop an "ultimate safe car" that can avoid collisions altogether.

The automakers already are releasing models with advanced safety features, but industry analysts say it will take time for the features to become popular, as they are currently too costly for buyers.
