Method and system for monitoring a vehicle driver includes an optical imaging system that obtains images of the driver, and a processor coupled to the optical imaging system and arranged to analyze the images obtained by the optical imaging system to locate a head of the driver in the images and monitor the driver's head or a part thereof over time. The processor also determines, based on the monitoring of the driver's head or part thereof, whether the driver has lost the ability to operate the vehicle. A reactive component is affected by the processor's determination that the driver has lost the ability to operate the vehicle, and requires action by the driver to indicate regaining of the ability to operate the vehicle or exerting control over the vehicle to slow the vehicle and bring it to a stop.

The vehicle of claim 1, wherein said processor is configured to analyze the information obtained by said information obtaining system and movement of the vehicle relative to a map to determine during movement of the vehicle and based on the obtained information and movement of the vehicle relative to the map, whether the driver has lost the ability to continue to control the vehicle. 10. The vehicle of claim 1, wherein said processor is configured to analyze the information obtained by said information obtaining system and movement of the vehicle relative to lane boundaries to determine during movement of the vehicle and based on the obtained information and movement of the vehicle relative to the lane boundaries, whether the driver has lost the ability to continue to control the vehicle. 11. The vehicle of claim 1, wherein the movement of the vehicle analyzed by said processor includes at least one of acceleration of the vehicle, an angle of a steering wheel of the vehicle and angular motion of the vehicle. 12. The vehicle of claim 1, wherein said processor is configured to analyze the information obtained by said information obtaining system and movement of the vehicle relative to traffic control elements to determine during movement of the vehicle and based on the obtained information and movement of the vehicle relative to the traffic control elements, whether the driver has lost the ability to continue to control the vehicle. 13. The vehicle of claim 12, wherein the traffic control elements include stop lights and stop signs. 14. The vehicle of claim 1, wherein said processor is configured to analyze the information obtained by said information obtaining system and movement of the vehicle relative to movement of other vehicles previously travelling the same road to determine during movement of the vehicle and based on the obtained information and movement of the vehicle relative to the movement of other vehicles, whether the driver has lost the ability to continue to control the vehicle. 15. The vehicle of claim 1, wherein said processor is configured to analyze the information obtained by said information obtaining system and movement of the vehicle by analyzing movement of the driver relative to movement of the vehicle to determine during movement of the vehicle and based on the relative movement of the driver to the vehicle, whether the driver has lost the ability to continue to control the vehicle. 16. The vehicle of claim 1, wherein said reactive component is configured to generate an audio or visual cue directed to the driver and requiring a responsive action by the driver to the generated audio or visual cue to indicate that the driver has regained the ability to operate the vehicle. 17. The vehicle of claim 16, wherein said reactive component is configured require a responsive physical action by the driver to the generated audio or visual cue to indicate that the driver has regained the ability to operate the vehicle. 18. The vehicle of claim 1, wherein said processor is trained in a training stage to recognize changes in driver behavior indicative of loss of ability to operate the vehicle. 19. The vehicle of claim 1, wherein said information obtaining system obtains information about the driver using ultrasonic or electromagnetic waves. 20. The vehicle of claim 1, further comprising a frame, said information obtaining system, said processor and said reactive system being arranged on said frame. 21.
