Don't forget, there is atmosphere between the laser and your car, and that beam will be diffused all over the place. So, a sensitive detector should be able to detect the presence of a specific wavelength of light, although normal background light may make detection impossible because your detector would be constantly going off. -- ______________________________________________________________________________ Earle A.
