Changing fonts on the federal freeways

Here's a great essay on the quest of two men to create a more legible road sign by finding the perfect font. The result? A new typeface called Clearview that can be read from 30% greater distance that the existing federal highway sign font, stodgily named "Series E-Modified." The font also reduces "halation," the glowing effect that renders reflective signs less legible when hit with your high beams.
