BMW's auto start/stop function

According to BMW the new auto start/stop function available in all new BMW is designed to help save fuel. The system will switch off the engine during a stop whenever the car stops at an intersection or in congested traffic. And, you guessed it right, the engine turns back on as soon as the brake pedal is released. This is a truly remarkable feature , however I am not very convinced it saves fuel.
