Why does perceived ambiguity in a typeset road sign increase sharply at higher speeds?

💡 Explanation

Because higher speeds reduce the available processing time for visual input, subtle kerning errors that merge letters become significant, leading to misidentification. Therefore, character differentiation decreases with poor kerning, rather than saccadic masking or accommodation, which are less directly linked to character spacing.
