blinded by light
I got blinded by a bike light this afternoon. Some stupidly bright
flashing thing, poorly aimed. How do I know it was poorly aimed? I was inside. At my desk. On the second floor. Looking 90 degrees away from the direction the bike was traveling. -- sig 69 |

Perhaps a bicycle size version of the U.S. Navy's " directed-energy laser weapon" which with a judicious selection of the frequency might be able to provide a solution to several "bicycle problems". Scalable power levels would efficiently provide. firstly, the ability to see after sundown at lower levels, and secondly, the problem of "dooring" and "Right Turn" accidents, at higher levels, by simply destroying the doors or vehicles making a right turn in the path of the bicycle. The technology is available and with the advent of the"e-bike" power is no longer a problem and it would, as well as providing almost perfect lighting for those night rides also eliminate those pesky bicycle accidents. -- cheers, John B. |

I could see that happening at night, but not during daylight hours. Have you recovered from the blinding light? Here's my experience while driving one day last year: I was driving on a 55 mph two-lane highway I occasionally ride. I saw a white light way up the road and wondered what it was. As I got closer, I realized it was a bicycle headed the same direction I was. The female rider had fastened a super-bright bike headlight to the back of her bike, facing backwards. Effectively, it was a white taillight, which is specifically illegal. It was aimed directly in my eyes, and bright enough that it really was blinding. I remember shading my eyes with my hand as I changed to the oncoming lane to pass her. It was almost as bad as driving into a setting sun. Now, I generally change lanes to pass bicyclists anyway. But I prefer to do it when I can easily see where I'm going. - Frank Krygowski |

wrote: And, I might add, eliminate the complaints of "lights in my eyes". There's a better and easier way that has been proposed many times and rejected every time. Install a horizontally polarizing screen over all headlights, and require riders, drivers, and pedestrians to wear vertically polarized glasses, which blocks the horizontally polarized light from the lights. As an added bonus, the glasses would also eliminate most forms of glare. I was marginally involved in a test of such a system while in college. As long as every vehicle used horizontally polarized lights, it worked very well. In fact, it worked too well. If everything was perfectly orthogonal (90 degrees), it was difficult to see the light source. So, the researchers had to rotate the polarization of both the headlights and glasses +/-10 degrees in opposite rotations, to insure that the headlights could be seen by at least one eye. There was also a problem with some traffic signal lights which produced mostly horizontally polarized light and were therefore difficult to see wearing the vertically polarized glasses. At the time (1968), seat belts were federally mandated for new cars. This precipitated a large numbers of "safety" proposals promoted by patent holders and manufacturers who wanted their products also made mandatory such as seat belt interlocks, shoulder belts, voice alerts, air bags, anti-lock brakes, helmets for drivers, redundant everything, etc. The light polarizing scheme got lost in the rush and confusion. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
