Led taillights are distracting, especially those with low refresh rates. The human retina takes 1ms to take a snapshot of the world, so lights with a refresh rate below 1000hz should be banned from the roads. Cadillacs in particular are bad, with refresh rates apparently around 60hz or so. I can usually spot caddies from a distance on the freeway at night due to how much their taillights flicker. It is extremely annoying, being the equivalent to flashing a light on and off rapidly, and distracts me away from the rest of the road. One such time nearly caused an accident as my attention kept getting distracted by an led taillight and I nearly missed an emergency brake in the lane ahead of me. Please ban all led taillights, or led taillights with a refresh rate below 1000hz.
