Stopping in a hurry | The Economist: "A number of carmakers already have or are introducing automated-braking systems. Germany’s Daimler uses a radar-based one in some of its Mercedes-Benz vehicles. Called Distronic, it also operates at high speed and adjusts both braking and acceleration to maintain a constant distance from other cars. If a collision seems likely a warning is given. When the driver puts his foot on the brake pedal the system automatically applies the optimum pressure required to avoid hitting the car in front. If the driver fails to respond, the brakes come on automatically.
