Thanks for your photos, mechBgon. They clearly show what I have been saying about bicycle lights and possible interference with other road users all along. You clearly demonstrate that, for a relatively low intensity light like a bicycle light and the position of the bicycle relative to the automobiles, it would be very, very difficult to cause any kind of glare problem for motorists.

On an interesting side note, the cutoff on the automobile lights that people obsess over doesn't seem make much difference as distance from the light increases. The lights from the car seem just a round as the light from the bicycle in both pictures. The cutoff may be important for close passing of other automobiles but as you get further from the light source, the cutoff becomes less important. Yet another thing we cyclists shouldn't worry so much about.
