Be careful about how seriously you take this article. Road and sign paint is highly reflective over a wide angle. While I haven't measured the paint, I am fairly certain it would greatly exceed that of E-Ink's technology; even after being baked, run over, rain and snowed on, and covered with dirt and solvents. Provided some miraculous survival technique allowed the electrophoretic strip to survive, it will still be compared to the paint's performance when being lit by headlights at a low angle some rainy night.
