What is claimed is: 1. Apparatus for installation in new motor vehicles or for retrofitting into an existing motor vehicle, comprising: an electric motor coupled to a drive shaft or drive axle of the vehicle; a controller for the motor; a first belt or a first drive chain for coupling said motor to one of said drive shaft or drive axle of the vehicle; and a sensor for determining rotational speed of said motor operatively connected to said motor, wherein said controller comprises means for disengaging power to said motor in response to an output of said sensor indicating said motor is rotating at greater than a predetermined speed. 2. The apparatus of claim 1, further comprising: an additional belt or drive chain coupled to the drive shaft or drive axle and extending in a direction opposite to that of said first belt or first drive chain; and an idler gear for engaging said additional belt or drive chain. 3. The apparatus of claim 1, wherein at least one of an existing vehicle battery and an auxiliary storage battery is used to power the motor to drive the vehicle during predetermined driving conditions. 4. The apparatus of claim 1, wherein said controller comprises means for disengaging power to said motor in response to operation of a brake pedal, provision of electrical energy to a reverse light, and shifting a transmission of said vehicle into a park position. 5. The apparatus of claim 1, wherein operation of said apparatus increases fuel economy of the vehicle, without interfering with the normal performance of the vehicle. 6. The apparatus of claim 1, provided as a kit of parts for installation on a vehicle. 7. The apparatus of claim 6, wherein the kit of parts is for retrofitting on an existing vehicle. 8. Apparatus for retrofitting into an existing motor vehicle, comprising: an electric motor coupled to a drive shaft or drive axle of the vehicle; a controller for the motor; and a sensor for determining rotational speed of said motor operatively connected to said motor, wherein said controller comprises means for disengaging power to said motor in response to an output of said sensor indicating said motor is rotating at greater than a predetermined speed. 9. The apparatus of claim 8, further comprising a first belt or a first drive chain for coupling said motor to one of said drive shaft or drive axle of the vehicle. 10. The apparatus of claim 8, further comprising: an additional belt or drive chain coupled to the drive shaft or drive axle and extending in a direction opposite to that of said first belt or first drive chain; and an idler gear for engaging said additional belt or drive chain. 11. The apparatus of claim 7, wherein at least one of an existing vehicle battery and an auxiliary storage battery are used to power the motor to drive the vehicle during certain driving conditions. 12. The apparatus of claim 8, wherein said controller comprises means for disengaging power to said motor in response to operation of a brake pedal, provision of electrical energy to a reverse light, and shifting a transmission of said vehicle into a park position. 13. The apparatus of claim 8, wherein operation of said apparatus increases fuel economy of the vehicle, without interfering with the normal performance of the vehicle. 14. The apparatus of claim 8, provided as a kit of parts for installation on a vehicle. 15. A motor vehicle equipped with the apparatus of claim 1. 16. A motor vehicle equipped with the apparatus of claim 8. 17. A method for controlling a vehicle equipped with the apparatus of claim 1, comprising using the apparatus to accelerate the vehicle for a predetermined time, to a predetermined speed or until other motive means are used. 18. A method for controlling a vehicle equipped with the apparatus of claim 8, comprising using the apparatus to accelerate the vehicle for a predetermined time, to a predetermined speed or until other motive means are used. 19. Apparatus for installation in new motor vehicles or for retrofitting into an existing motor vehicle, comprising: an electric motor coupled to a drive shaft or drive axle of the vehicle; a controller for the motor; a first belt or a first drive chain for coupling said motor to one of said drive shaft or drive axle of the vehicle; an additional belt or drive chain coupled to the drive shaft or drive axle and extending in a direction opposite to that of said first belt or first drive chain; and an idler gear for engaging said additional belt or drive chain.
