Over the next 30 years, all kinds of technologies were introduced to reduce these numbers. Airbags, ABS brakes, electronic stability control, adaptive cruise control, other early level ADAS, improved tires and many other items helped drive down the accident rate. By 2011, the fatality rate was down to 32,479, with 29,867 crashes involving 44,119 vehicles. 10.5 people of every 100,000 people in the country were killed on the highway, despite higher congestion, higher population and more powerful cars.
