The system of claim 1, wherein said processor is arranged to predict a collision between the first and second vehicles based on their position and speed. 3. The system of claim 2, wherein said processor is arranged to determine the speed of the second vehicle from the position information. 4. The system of claim 1, further comprising: a second positioning system arranged in the second vehicle for determining the position of the second vehicle; and a communication device arranged in the second vehicle and which communicates the position of the second vehicle as determined by said second positioning system to the first vehicle. 5. The system of claim 4, wherein said processor is arranged to predict a collision between the first and second vehicles based on their position and speed and said communication device is arranged to communicate the speed of the second vehicle to be received by said receiver on the first vehicle. 6. The system of claim 1, further comprising a determining system fixed on infrastructure for determining the position and optionally speed of the second vehicle and an infrastructure-to-vehicle communication system coupled to said determining system for communicating the position and optionally speed of the second vehicle to the first vehicle for use by said processor. 7. The system of claim 1, further comprising a second reactive component or system arranged in the first vehicle and coupled to said processor, said processor including information about right-of-ways of vehicles travelling on the at least one lane and the at least one intersecting lane at the intersection and being arranged to control said second reactive component based on the information such that said second reactive component or system is arranged to initiate an action or change its operation in consideration of the right-of-ways at the intersection. 8. The system of claim 1, further comprising an automatic driving and guidance unit arranged in the first vehicle and coupled to said memory unit and a steering unit and acceleration unit arranged in the first vehicle for guiding the first vehicle within the edges of the at least one lane of the roadway and through the intersection. 9. The system of claim 1, wherein said first reactive component or system is an alarm or a vehicle guidance system for automatically guiding the first vehicle. 10. The system of claim 1, wherein each of the first and second vehicles is an automobile or truck. 11. The system of claim 1, wherein the first and second vehicles are airplanes. 12. A method for preventing vehicle accidents at intersections, comprising determining the position of a first vehicle using a processor; storing data in the first vehicle relating to edges of at least one lane of a roadway on which the first vehicle may travel and edges of at least one intersecting lane at an intersection; receiving position information in the first vehicle about a second vehicle in an intersecting lane to the lane in which the first vehicle is traveling; predicting a collision in the first vehicle between the first vehicle and the second vehicle based on the position of the first and second vehicles using a processor; and initiating an action in the first vehicle or causing a change in the operation of the first vehicle if a collision is predicted by the processor. 13. The method of claim 12, further comprising using a processor for predicting the collision between the first and second vehicles based on their speed. 14. The method of claim 13, further comprising using a processor for determining the speed of the second vehicle in the first vehicle from the position information about the second vehicle. 15. The method of claim 12, further comprising: determining the position of the second vehicle in the second vehicle using a processor; and communicating the position of the second vehicle from the second vehicle to the first vehicle using a communications device. 16. The method of claim 12, further comprising: determining the position and optionally speed of the second vehicle using an infrastructure-based system; providing an infrastructure-to-vehicle communication system that can communicate with the first vehicle; and communicating the position and optionally speed of the second vehicle as determined by the infrastructure-based system from the infrastructure-to-vehicle communication system to the first vehicle for use in collision prediction by the processor. 17. The method of claim 12, further comprising: providing the processor with information about right-of-ways of vehicles travelling on the at least one lane and the at least one intersecting lane at the intersection; and generating commands at the processor to initiate an action in the first vehicle or cause a change in the operation of the first vehicle based on the information about the right-of-ways at the intersection. 18. The method of claim 12, further comprising using a processor for guiding the first vehicle within the edges of the at least one lane of the roadway and through the intersection. 19. The method of claim 12, wherein each of the first and second vehicles is an automobile or truck. 20. The method of claim 12, wherein the first and second vehicles are airplanes. 21.
