I thought I was the only one suffering these symptoms when dealing with LED tail lights.
Everyone else I've mentioned this can barely grasp the concept of seeing a a "sea of lights" flooding your field of vision whenever your eyes does saccadic movements.
It's really annoying and drives me crazy. I live in Brazil so thankfully LED tail lights aren't still popular here yet as our cars suck. But I figure that if all cars had that, it might even compromise my ability to drive properly at night.
