So, just finished reading an article on WaPo about fireflies/lightening bugs and got me thinking further… Car headlights suck. They mess up our night vision when we pass another dickhead running white/blue lights. We mess up the habit(at) of many animals/bugs. So why not red lights? My hiking/camping headlamp has a red light option, which is the only function I use, and I can see fine. Why the FUCK do we still have these ungodly bright white/blue lights?
It’s because car light colors are actually just the Doppler Effect in action. When a car is coming toward you, its lights look white. When it’s moving away, its lights look red. This is also why when your wife or girlfriend is shrieking and running towards you with a knife, her voice sounds very high.
