The Short Version
Illinois introduced a bill to ban drivers from wearing smart glasses that display visual content in their line of sight, potentially becoming the first US state to do so.
Illinois is moving to ban smart glasses behind the wheel, targeting any device that puts visual content directly in a driver's line of sight. Navigation is the feature that makes smart glasses worth wearing daily, so a law that strips it from drivers doesn't just limit one use case, it removes the main reason most people would buy the glasses in the first place. If other states copy Illinois, companies building turn-by-turn directions into their frames are designing for a shrinking audience.
