I mocked this circuit up to make a circuit in real life for my daughters power wheel toy. I put in a big battery and a remote kill switch; it is awesome but the power wheel has a on off pedal so it is either full speed or no speed. When my daughter presses pedal it jerks her back hard due to the torque of the motor with the new battery. This circuit will allow for a smooth start and instantaneous stop; the best of both worlds.
