In case you are not already aware of this, the tail lights of some newer model passenger automobiles are visually distracting because the light emitting diode (led) array that is used for the tail lights is being strobed on and off, instead of being on continuously. I have noticed this on the latest model Cadillac and Jaguar vehicles, to name two. The rate of strobing is high enough so that you don't see the flashing when looking directly at the taillight. However, as my eyes move to scan multiple lanes of highway traffic ahead, I can see the strobing in my peripheral vision and my first reaction to the sudden flash is that the brake lights have come on. It catches my attention and tricks my eyes to look back at that particular vehicle to confirm whether or not it is indeed braking. This is distracting. The newer led vehicle tail lights should be illuminated continuously (just like a good old fashion light bulb), not strobed on and off at a high rate.
