90% of car accidents can be attributed to human error, according to the National Highway Traffic Safety Administration. In an effort to reduce such occurrences, the NHTSA is instilling ideas to carmakers on how to incorporate new technologies that would encourage safe driving habits. This includes the Driver Alcohol Detection System for Safety, which uses sensors in the cabin to measure blood-alcohol content by breath or touch. Other technologies, which already exist, include collision warning and automatic braking systems, and transmissions that do not operate when a passenger isn’t wearing a seatbelt. Some of these technologies were on display at the now-concluded LA Auto Show. In a change of tone, carmakers, which previously resisted installing safety features, are working with the NHTSA in developing new features and providing them to the consumer.
