Driving on today's expressways is as dangerous as ever. Drivers face the daily challenges of extremely congested roads and distractions from cell phones, passengers, and even in-vehicle DVD systems. As we all know, this combination can lead to a reduced focus on the road.

Over the years, automotive manufacturers have taken several steps to help keep motorists safe. This has typically been achieved through the use of passive-restraint systems that protect the driver and passengers, but only after a collision has occurred. The most notable passive safety feature is undoubtedly the seatbelt, which has saved more than 168,500 lives. Another passive safety technology, the airbag, which recently celebrated its 20th anniversary, has also been credited with saving more than 12,000 lives.
