Cars have laws regarding use of lights. I've been pulled over for having my fog lights on. I get annoyed at the folks who have extra bright lights on their cars when I drive, and at SUVs whose headlights are above my eye-level.

There is a balance between seeing everything and not interfering with others that plays out in cars. It will play out in bicycles and MUPs too, and by laws if we don't figure out a good way to balance.

Keep pissing each other off enough, and there'll be laws about it.
