We take seat belts, anti-lock brakes and air bags for granted these days, but each of these technologies was born from the persistent desire to reduce accident fatalities and injuries on the road. If we look at virtually any vehicle today, it is furnished with an abundance of mechanisms aimed to heighten safety – from automatic headlamps to traction control to lane departure systems. These driver-assistance technologies enhance convenience but also save lives.
