I agree wholeheartedly...At 5 mph and below when the car is in Drive, the engine is still driving the rear wheels, attempting to push the car along. So stepping on the brakes in Drive means not only having to overcome the momentum of the vehicle, but also the drive force of the rear wheels. Popping the car into neutral at 5 - 10 mph eliminates the extra push from the rear wheels and reduces the pressure necessary on the brakes to stop the car. Slowing down from above 10 mph, there are benefits of utilizing engine braking by removing your foot from the accelerator pedal.


I've noticed that stepping on the brakes on very slippery roads with the car in Drive, the front wheels tend to lock up and slide (losing steering control) while the rear wheels are still turning and pushing the car forward.


My experience is with nearly 20 yrs driving experience in Wisconsin, Illinois and New York snow - and 15 yrs in Oklahoma ice storms.
